How are electricity and magnetism related?
The discovery that electricity and magnetism are closely related goes as far back as the 1820s, when physicist Hans Christian Oersted demonstrated that an electrical current creates a magnetic field capable of deflecting a compass needle. Oersted’s discovery established that there is more than just one type of magnet.
Why is an electromagnet no longer magnetic?
The electromagnet is no longer magnetic. Because electromagnets rely on an electric current, once their electric energy source is removed, it turns off. Now that you’ve created a simple electromagnet, imagine how its properties are used in real-world applications.
What are the three types of magnets?
In fact, you may know from our previous articles that magnets can fall into three categories: permanent, temporary and electromagnet.
Do permanent magnets have magnetism?
Theoretically, permanent magnets maintain their magnetism forever while temporary magnets are not really magnets at all but can present magnetic behavior when in the presence of a strong magnetic field. Electromagnets, which we can thank Oersted for, produce magnetism only when in the presence of an electric current.

How do temporary magnets work?
A temporary magnet gets magnetic properties and behaves like a magnet when placed in a strong magnetic field. The magnetic properties disappear when you remove them from the magnetic field. You can test this property by attaching a permanent magnet with a nail and picking up paper clips. Though a nail, by default, does not have any magnetic field, ...
How do magnets control their strength?
The magnet’s strength can also be controlled by the number of coils wrapped on the ferromagnetic core, the amount of electricity passing through the coil or even by the material chosen to form the core. You can extend this science experiment by altering one of these materials.
What happens when electricity passes through a coil wrapped around a nail?
When electricity passes through the coil wrapped around the nail, the moving charges produce a magnetic field. If the current flows through a straight wire, it produces a circular magnetic field around the wire.

Who discovered the magnetic field?
Danish scientist Hans Christian Ørsted discovered in 1820 that electric currents create magnetic fields. British scientist William Sturgeon invented the electromagnet in 1824. His first electromagnet was a horseshoe-shaped piece of iron that was wrapped with about 18 turns of bare copper wire (insulated wire didn't exist yet).
Do electromagnets need electricity?
However, unlike a permanent magnet that needs no power, an electromagnet requires a continuous supply of current to maintain the magnetic field. A simple electromagnet consisting of a coil of insulated wire wrapped around an iron core.

How to wrap a battery wire?
Before you start wrapping the wire, leave a strand of wire loose from the iron that will attach to the battery that's about 2–3 inches (5.1–7.6 cm) long. Position the wire so that it’s perpendicular to the iron core and at one end. 4. Wrap insulated copper wire around the iron going in one direction.
How to wrap wire around iron?
1. Choose an iron nail or screw as the core. Pick out a piece of iron that you have around your home, such as a nail, screw, or bolt. Choose an iron item 3–6 inches (7.6–15.2 cm) in length so that there’s plenty of room to wrap the wire around the iron object.
How to wrap wire in different directions?
5. Push the wire close together as you’re wrapping it.

Wrap insulated copper wire around the iron going in one direction. Create an ongoing spiral around the piece of iron to conduct the electricity. Wrap the wire in one continuous strand, going in one direction, so that there’s a strong electrical current.
How to make a magnet stronger?
Add more wraps of wire to form a stronger magnet. The more coils you create, the stronger the electric current. Get a large spindle of wire and make as many wraps as you can around an iron nail or screw to create a very powerful magnet, adding several layers of wire on top of one another, if desired.

What is the effect of magnetic current on a moving magnet?
Electrical current generates a magnetic field and creates an electromagnet, but a moving magnet can also generate electrical current in a closed loop of conducting wire. This effect, discovered by Michael Faraday and Joseph Henry, is called magnetic induction and is central to how electric generators work.
How does a wire coil work?
Once the motor is created, the wire coil will spin about the axle of the motor. By experimenting with the size of the coil, students can examine the relationship between the strength of the electromagnetic field, the number of loops in the coil, and the speed at which the motor spins.
What causes a battery to spin around?
This creates a closed circuit when the wire touches both the battery and the magnet (that is touching the bottom of the battery). The electrical current that flows through the wire interacts with the magnet's magnetic field, resulting in a force that pushes on the wire and causes it to spin around the battery.
