1 Chapter 30. 2 Mutual Inductance Consider a changing current in coil 1 We know that B 1 = 0 i 1 N 1 And if i 1 is changing with time, dB 1 /dt= 0.
Electromagnetic Induction. Magnetic Fields Can Move Charges A moving charge or a group of moving charges (a current) produce a magnetic field—flowing.
E-field lines originate on positive charges and terminate on negative charges (Gauss’ Law) B-field lines always form closed loops. Changing B-field.
Electromotive Force Revisited When we say something has energy, it can do work Electric potential is the potential energy per unit charge: the amount of.
