Faraday's Law

Question 1

The change in magnetic field in the coil can be quantified as

Answer 1

Change in/Changing magnetic flux

Question 2

Factors affecting Direction of the Induced Current

Answer 2

A. The direction of the induced current is opposite the movement of the
magnet.

B. When the magnet is at rest, the galvanometer shows zero reading.

Question 3

Factors affect induced EMF and current

Answer 3

1. Strength of the magnet.
2. Increasing the motion of the magnet.
3. The number of turns of the coil.

Question 4

He noticed that when he moved a permanent magnet in and out of a coil or loop of wire, it induced an electromotive force or emf, in other words a Voltage, and therefore a current was produced.

Answer 4

Michael Faraday

Question 5

Two laws of electromagnetic induction

Answer 5

A. Whenever there is a change in the magnetic flux relative to the coil, an
electromotive force is induced.

B. The magnitude of the induced electromotive force is directly proportional to the rate of change of the magnetic flux linked with the coil.

Question 6

The amount of magnetic field lines through a given conductor.

Answer 6

Magnetic Flux

Question 7

Factors affecting the magnitude of EMF and current

Answer 7

1. Strength of the magnet/change in magnetic flux.
2. Increasing the motion of the magnet.
3. Number of turns of the coil.
