1
Faradays Law of Induction A changing magnetic field induces an electric field. The induced electric field causes a current to flow in a conductor.

2
Lenzs Law A changing magnetic field induces a current, which in turn produces a second magnetic field which opposes any further change in the first.

3
Application of Lenzs Law magnetic field A magnet is pushed into a coil as shown below. What is the direction of the induced magnetic field in the coil?

4
Application of Lenzs Law current induced A magnet is pushed into a coil as shown below. What is the direction of the current induced in the coil?

5
Application of Lenzs Law A magnet is pushed into a coil as shown below. What is the direction of the current induced in the coil?

6
Application of Lenzs Law magnetic field A magnet is pushed away from a coil as shown below. What is the direction of the induced magnetic field in the coil?

7
Application of Lenzs Law current induced A magnet is pushed into a coil as shown below. What is the direction of the current induced in the coil?

8
Application of Lenzs Law A magnet is pushed into a coil as shown below. What is the direction of the current induced in the coil?

9
primary coil iron core Transformers Given the current as shown in the primary coil, determine the direction of the magnetic field induced in the iron core.

10
Transformers Given the current as shown in the primary coil, determine the direction of the magnetic field induced in the iron core.

11
induced magnetic field secondary coil Transformers Given the induced magnetic field as shown, determine the direction of the current induced in the secondary coil.

12
Transformers Given the induced magnetic field as shown, determine the direction of the current induced in the secondary coil.

13
For a transformer, P P = P S I P V P = I S V S I P / I S = V S / V P = N S / N P
