Hi,(adsbygoogle = window.adsbygoogle || []).push({});

My question:

A 22.0 cm diameter coil consists of 20 turns of circular cooper wire 2.6mm in diameter. a uniform magnetic field, perpendicular to the plane of the coil, changes at a rate of 8.65 x 10^-3 T/s. Determine the current in the loop.

I'm not sure how to approach this equation. I was thinking I should use the following equations:

R=((rho)L)/A, to find the resistance

Emf=-N(magnetic flux)/t, for the voltage

then using the resistance and voltage that I found from the equations use them to find the current, I.

I=(V)/R

Is anyone of this correct

Thank You
