What is the strength of the magnetic field around a magnet?
The strength of the field varies depending on its location around the magnet. The magnetic field of a bar magnet is strongest at either pole of the magnet. It is equally strong at the north pole when compared with the south pole. The force is weaker in the middle of the magnet and halfway between the pole and the center.
Why is the magnetic force strongest at the north and South Poles?
Why the Magnetic Force Is Strongest at the North and South Poles. The dipole tries to align itself with a magnetic field, but at the ends of a bar magnet, the field lines are very close together. What this indicates is that the magnetic field varies strongly over a short distance compared to the variation closer to the middle of the magnet.
What happens to the magnetic field strength of a bar magnet?
The magnetic field strength of the bar magnet through intense at the poles will start faltering as the distance between the poles increases. The tiny dipoles inside the bar magnet always align themselves in the direction of the Earth’s magnetic field, hence the spins are oriented towards each pole.
How can a bar magnet be used to find the direction?
The magnetic dipoles inside the bar magnet experience the magnet force due to the Earth’s magnetic field and align in the direction of the field. Hence, a bar magnet can therefore be used to find the direction same as a compass. 1) Rectangular bar magnet: This magnet has four rectangular faces painted and two square shape poles.

Where the magnetic field is strongest in a bar magnet?
polesThe magnetic field is strongest near the poles of the magnet. It is equally strong at both the poles.
Where is the magnetic field the strongest on a bar magnet and why?
the magnetic field lines never cross each other. the closer the lines, the stronger the magnetic field (so the magnetic field from a bar magnet is strongest closest to the poles)
Where is the magnetic field the strongest and weakest?
The magnetic field varies in strength over the earth's surface. The Earth's magnetic field is weakest at the equator and strongest at the poles.
Why is the magnetic field the strongest near the poles?
The closer the magnetic field lines are, the stronger the magnetic field at that point. As we can see in the diagram, the magnetic field lines are closer or denser at the poles. So, the magnetic field is strongest around the poles of the magnet.
Where is the magnetic field strongest in a bar magnet class 10?
pole(1) The part of a bar magnet, at which the magnetic field is the strongest, is called its pole.
Where is the magnetic field strongest in a bar magnet and in a solenoid?
The magnetic field is strongest inside the coil of a solenoid. Inside the coil of a solenoid the magnetic field lines are uniform and tightly packed together which creates a stronger magnetic field here than anywhere outside of the solenoid.
What are the different uses of bar magnets?
A bar magnet is used for various purposes may be industrial, electronics, chemical industries, laboratories, etc.
Why does bar magnet have the North Pole and the South Pole?
When the bar magnet is suspended in the air, it will continuously show harmonic motion until it gets aligned in the direction of the Earth’s magnetic field.
What happens to the magnetic force line in a bar magnet?
In a bar magnet, the closer it is to the magnet’s N and S poles, the denser the magnetic force line. It can be seen that the magnetic field gets stronger as it approaches the pole of the magnet and more weakens as it moves away from the pole of the magnet.
What is the magnetic field around a magnet?
Magnetic field around magnet. The space where the magnetic force of the magnet acts is called a ‘magnetic field.’. The direction of the magnetic field is determined in the direction indicated by the N pole of the magnetic needle placed at that point. The magnetic field is invisible to the eye, but you can check the magnetic field by looking at ...
How to tell if magnetic field is strong?
The magnetic field is invisible to the eye, but you can check the magnetic field by looking at the iron powder’s arrangement when you sprinkle it around a magnet. The magnetic field expressed as a line is called a ‘magnetic force line.’. When the magnetic field is strong, the magnetic force lines appear dense, and where the magnetic field is weak, ...
What is the force between two magnetic objects?
The Magnetic force acts between two magnetic objects. Unlike gravity, the magnetic force has not only a pulling but also a pushing. A pulling force acts between the different poles. Between the same poles, there is a pushing force. You can also check the force’s direction with the magnetic force line. In the different poles, a line is connected ...
Where is the magnetic field strongest?
The strength of the field varies depending on its location around the magnet. The magnetic field of a bar magnet is strongest at either pole of the magnet. It is equally strong at the north pole when compared with the south pole. The force is weaker in the middle of the magnet and halfway between the pole and the center.
Why are the field lines at the ends of a bar magnet so close together?
What this indicates is that the magnetic field varies strongly over a short distance compared to the variation closer to the middle of the magnet. Because the magnetic field changes so dramatically, ...
What is the purpose of a bar magnet?
The magnetic field gets weaker the farther you get from either pole, so a bar magnet is only useful for picking up small items over short distances.
Where is the force weaker in a magnet?
The force is weaker in the middle of the magnet and halfway between the pole and the center. If you were to sprinkle iron filings on a piece of paper and place the magnet beneath it, you could see the path of the magnetic field lines. The field lines are closely packed at either pole of the magnet, widening as they get farther from ...
Why do iron filings make a pattern tracing field line?
Iron filings make a pattern tracing field lines because each bit of iron is itself a tiny dipole (the separation between magnetic fields). The force the dipole experiences is proportional to the strength of the dipole and proportional to the rate at which the magnetic field changes.
What is a bar magnet?
Bar magnets are permanent magnets. This means that their magnetism is there all the time and cannot be turned on or off as it can with an electromagnet. Opposite (unlike) poles attract, and like poles repel. If permanent magnets are repeatedly knocked, the strength of their magnetic field is reduced.
What are the two poles of a bar magnet?
Bar magnets have two poles: 1 north pole – normally shown as N 2 south pole – normally shown as S
Why do magnets and electromagnets occur?
Magnetism and electromagnetism occur because of the magnetic fields around magnets and around electric currents.
What is the term for the process of converting a magnet to a non-magnet?
If permanent magnets are repeatedly knocked, the strength of their magnetic field is reduced. Converting a magnet to a non-magnet is called demagnetisation. Magnets are made from magnetic metals – iron, nickel and cobalt.
What are some substances that can be permanently magnetized?
Substances that can be permanently magnetised are described as magnetically hard. These are often alloys of iron, nickel and cobalt. Substances that can only be temporarily magnetised are described as magnetically soft. Iron is magnetically soft – it can be easily magnetised and demagnetised.
Can metals be turned into magnets?
These are the only pure metals that can be turned into a magnet. Steel is an alloy of iron and so can also be made into a magnet. If these metals have not been turned into a permanent magnet they will still be attracted to a magnet if placed within a magnetic field.
Can we see magnetic fields?
Although we cannot see magnetic field lines, we can detect them using iron filings. The tiny pieces of iron line up in a magnetic field.
Where is the magnetic field strongest?
The field will be strongest close to the end poles of the magnet. If it is uniformly magnetised this will be at the face of each end of the bar magnet. Inside the magnet itself the magnetic field will also be strong, but that would be inaccessible to normal experiments.
What is the strongest magnet?
Without a doubt, the strongest magnets AT ROOM TEMPERATURE are neodymium-iron-boron 2:14:1 and, over (near) 120 celsius degree the strongest magnets are samarium-cobalt 1:5.
What is the strongest material for permanent magnets?
The “strongest” type of material for permanent magnets, is the kind of “HARD” FERROmagnetic or FERRImagnetic material with the highest value of “ magnetic energy density product ”, BHmax.
What is the optimal location for monitoring global ionospheric conditions?
LEO is the optimal location for monitoring global ionospheric conditions (electron density, currents,instabilities), thermospheric parameters (temperature, composition, winds, waves), and the characterizing parameters of the ionospheric electrodynamics (auroral and higher-energy electron precipitation location,intensity, and dynamics).

This refers to the Sun and our Sun throws out a spiral magnetic field that engulfs the Earth and reaches towards the entire Solar System.
Which field is the most dense?
The magnetic field is the most dense at the center of the bar. as shown in the figure. Field density depend upon permeability of the medium. In lower permeable medium field becomes rarer and vice vis. Magnetic field line completes circle always, around its mother electric field . It can be represented by an electric coil wound on the magnetic core, caring the direction of electric current flow.
