Magnitude of the induced current can be increased by 1. increasing the number of coils of the wire. 2. by increasing the power of magnet.
- Taking the conductor in the form of a coil of many turns of insulated wire.
- Increasing the strength of the magnetic field used.
- Increasing the rate of change of magnetic flux associated with the coil.
How does the strength of induced current increase with increasing magnetic field?
The strength of the induced current increased when the strength of the magnetic field increases. It will also increase when the number of turns is increased or if the speed of the conductor increases.
What does the magnitude of induced current depend on?
The magnitude of the induced current depends on the rate of change of magnetic flux or the rate of cutting of the magnetic field lines. 1. The number of turns of the coil
What is induced current and why does it flow?
This current flows because something is producing an electric field that forces the charges around the wire. The induced current depends on both the area of the coil and the change in a magnetic field. The magnitude of the induced current can be increased by: Taking the conductor in the form of a coil of many turns of insulated wire.

What affects the magnitude of induced current?
The magnitude of the induced current depends on the rate of change of magnetic flux or the rate of cutting of the magnetic field lines.
How do you increase magnitude?
An increase of two orders of magnitude is the equivalent of multiplying by 100, or 102. In general, an increase of n orders of magnitude is the equivalent of multiplying a quantity by 10n. Thus, 2,315 is one order of magnitude larger than 231.5, which in turn is one order of magnitude larger than 23.15.
What is the magnitude of induced current?
The answer is 0 because for any current to be induced, it needs to have a change in flux. The wire carries a steady current so there will be no change in flux.
What are the factors affecting the magnitude of the induced emf and the magnitude and direction of the induced current in Faraday's Law?
The induced e.m.f. is directly proportional to A, the area of cross-section of the coil. The induced e.m.f. is directly proportional to B, the strength of the magnetic field in which the coil is rotating. The induced e.m.f. is directly proportional to 'w', the angular velocity of coil.

How do you change the magnitude of a vector?
The formula for the magnitude of a vector can be generalized to arbitrary dimensions. For example, if a=(a1,a2,a3,a4) is a four-dimensional vector, the formula for its magnitude is ∥a∥=√a21+a22+a23+a24.
What does magnitude mean in physics?
the maximum extent of sizeIn Physics, magnitude is defined as the maximum extent of size and the direction of an object. Magnitude is used as a common factor in vector and scalar quantities. By definition, we know that scalar quantities are those quantities that have magnitude only.
What are the three factors that determine the amount of induced current?
Electromagnetic induction is when a voltage is created by passing a conductor through a magnetic field....The size of the voltage can be varied by three factors:The size of the magnetic field. ... The active length of the conductor. ... The speed at which the conductor passes through the field.
On what factors does the magnitude of induced emf depend?
The induced emf is directly proportional to the number of turns, magnetic field, area and the time in which the magnetic flux changes. Therefore, the magnitude of the induced emf depends on the change in magnetic flux and also on the time in which the magnetic flux changes.
On what factors the direction of induced current depends?
Two Factors are : 1. The change in magnetic flux and 2. The time in which the magnetic flux changes. DIRECTION of induced e.m.f depends on whether the magnetic flux increases or decreases.
What is induced current?
A current can be induced in a conducting loop if it is exposed to a changing magnetic field. A current can be induced in a conducting loop if it is exposed to a changing magnetic field.
What happens to the magnetic field when the current in a wire increases?
In other words, if the applied magnetic field is increasing, the current in the wire will flow in such a way that the magnetic field that it generates around the wire will decrease the applied magnetic field. Ammeter. Magnetic Field. Coil Shape.
How does the strength of a current vary?
The strength of the current will vary in proportion to the change of magnetic flux, as suggested by Faraday’s law of induction. The direction of the current can be determined by considering Lenz’s law, which says that an induced electric current will flow in such a way that it generates a magnetic field that opposes the change in the field ...
Why does changing the coil shape of an ammeter produce higher readings?
Since the strength of an induced current depends in part on the rate of change in the magnetic flux, changing the coil shape very quickly produces higher readings on the Ammeter than when the coil is adjusted slowly. Last modified on 17 June 2019. back to top.
What is the effect of induced current?
As with all currents, the induced current creates a magnetic field around itself. Note that this magnetic field opposes the original change. For example, if a magnet is moved into a coil of wire, the induced magnetic field tends to repel the magnet back out of the coil.
What factors affect the induced potential difference?
Factors affecting the induced potential. The direction of the induced potential difference or induced current depends on the direction of movement. The current is reversed when: the magnet is moved out of the coil. the other pole of the magnet is moved into the coil. The images illustrate how this works.
What is the term for the potential difference between a conductor and a magnetic field?
A potential difference can be induced (created) in a conductor when there is movement between the conductor and a magnetic field. This can occur in two different ways: This is called electromagnetic induction and is often referred to as the generator effect.
What is the effect of a magnet?
a magnet is moved into a coil of wire. This is called electromagnetic induction and is often referred to as the generator effect. The induced voltage produces an induced current if the conductor is connected in a complete circuit. As with all currents, the induced current creates a magnetic field around itself.
How does a change in the magnetic field affect a transformer?
A change in the magnetic field through a coil can induce a potential difference across it which drives a current. The voltage and current changes in a transformer can be calculated, as power transfer is constant.
How is potential difference created?
A potential difference can be induced (created) in a conductor when there is movement between the conductor and a magnetic field. This can occur in two different ways: 1 a coil of wire is moved in a magnetic field 2 a magnet is moved into a coil of wire
