Homework Statement


Is the magnetic force on the wire loop in a direction tha would tend to increase or decrease the change in net flux through he wire loop.(This situation has a solenoid with current running through it right next to it, the current is being turned on and off.)


Homework Equations



flux=integral of B dot dA
induced emf=-N time the derivative of flux with respect to time

The Attempt at a Solution


I have my force vectors, and my magnetic moments, and Isee they are in the same direction, and I have found the induced emf, and current, but I don't see the relationship between the magnetic force on the loop and the change in flux. Could someone help point me out in the right direction here.

I feel like the best thing I could do would be to find an equation to plug in for B that is in terms of force but I have no such equation.

Thank you.
