1. The problem statement, all variables and given/known data
A long solenoid (black coil) with crosssectional area A cm^2 and length L is wound with n1 turns of wire. A timevarying current i1 flows through this wire. A shorter coil (blue coil) with n2 turns of wire surrounds it. Use (uo)(m*kg/s^2*A^2) 1) Find the value M of the mutual inductance. Note: The current in coil 1 is constantly changing. However, when using the hints it may help you to consider the instant at which the current in coil 1 is A. I dont exactly know how to post the image 2. Relevant equations I used the above equation 3. The attempt at a solution I got M = P*n1*n2*A/L but it was wrong. Not sure where I went wrong. Any help would be appreciated

if a pic is necessary, i can probably describe it
