1. Electromagnetic Induction (Lenz’s Law)

2. Lenz’s Law
The induced emf (voltage) resulting from a changing magnetic flux produces a direction of current so that the induced current produces a magnetic field that opposes the original change in magnetic flux!
Say What?

9. Mutual Induction Changing the current in one loop induces a change in another loop.
Vs/Vp = Ns/Np = Ip/Is

10. Self Induction e = -L (DI/Dt)
Only responds to
Changing current
Crossovers
E = ½ L I2
