Electromagnetic induction

1. Magnetic flux. Positive and negative flux. Magnetic flux linkage.

2. Induced EMF and Faraday's flux law.

3. Induced EMF caused by time dependent magnetic field. Magnitude or direction.

4. Change of geometry and motional EMF. Rotating coil.

5. Motional EMF is created by Lorentz force.

6. Lenz's law.

7. Eddy currents and magnetic braking . Lenz's law.

8. Eddy currents and induction heating.

9. Transformers. Flux per turn conservation for ideal transformer. Efficiency.
