Homework Statement



The component of the external magnetic field along the central axis of a 50 turn coil of radius 4.7 cm decreases from 1.8 T to 0 T in 4.3 s.

If the resistance of the coil is 2.8 , what is the magnitude of the induced current in the coil?

Homework Equations





The Attempt at a Solution



E=50*(1.8T*pi*.047sqrd)/.43

I am confused on how you incorporate the resistance

The question asks you to find the induced current, not just the emf. How do you find current from emf?
