Worked Example: Mutual Inductance
Google ClassroomLet's solve a couple of questions on Mutual Inductance. The first question is about figuring out the value of Mutual Inductance given a current and flux, and the second is about a factor which affects Mutual Inductance.

In the problem why is self inductance completely ignored? From Faraday's second law we should get, dΦ/dt = di/dt and the complete equation of EMF is -> E1 = -M12(di2/dt) - L1(d1/dt). Since those aren't taken into account wouldn't the value we get be inaccurate?(1 vote)- In the problem why is self inductance completely ignored?
