Homework Statement
A uniform magnetic field B is confined to a cylindrical volume of radius 0.080m. B is directed into the plane of the paper and is increasing at a constant rate of (delta)B/(delta)t=0.300 T/s. Calculate the magnitude and direction of the current induced in a circular wire ring of radius 0.16m and resistance 1.4 Ohms that encircles the magnetic field region.
Homework Equations
The Attempt at a Solution
step1: find emf through wire ring using magnetic flux of cylinder?
step2: R(resistance)=1.4Ohms, use equation I=emf/R to find magnitude. and direction is going to be counter clockwise to appose change in flux.
Not sure how to go about starting on this problem. Help please.
