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?

3 Lenz’s law X

4 Lenz’s law X

5 Lenz’s law X

6 Lenz’s law X

7 Lenz’s law X

8 Lenz’s law X

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
