## Homework Statement

A 0.100m long solenoid has a radius of 0.05m and 15000 turns. The current in the solenoid changes at a rate of 6.0 A/s. A conducting loop of radius 0.0200m is placed at the center of the solenoid with its axis the same as that of the solenoid. Determine the mutual inductance of this combination.

## Homework Equations

E

_{s}=-M([tex]\Delta[/tex]I

_{p}/[tex]\Delta[/tex]t)

## The Attempt at a Solution

The answer has to be the induced emf divided by the rate of current change(6 A/s), but I just don't understand where and how we can glean the emf from the information given. I'm having a hard time on this emf stuff. I thought I understood very well how and when it is induced, but this is the second instance that I've had to solve for two variables and I just don't know how my teacher expects us to do it.
