Here is a bonus question that I was given yesterday. I am completely at a loss of what to do. Any suggestions?(adsbygoogle = window.adsbygoogle || []).push({});

A conducting loop with a half circle of radius r=0.20m and 3 straight sections. The half circle lies in a uniform field B that is directed out of the page. The magnitude of B as a function of time is given by B(t) = 4.0t^2 + 2.0t + 3.0 where B is in Teslas and t is in seconds. An ideal battery with EMF E=2.0V is connected to the loop. The loop has a resistance of 2.0 Ohms.

a) Find the magnitude and direction of the EMF induced in the loop.

b) What is the current in the loop at t = 10 seconds?
