Problem: A flat, circular, steel loop of radius 75 cm is at rest in a uniform magnetic field, as shown in an edge-on view in the figure. The field is changing with time, according toFind the emf induced in the loop as a function of time (assume t in seconds). Express your answer in terms of the variable t.

Induced emf:

ε(t)=ddtϕ=ddtBAcosθ

A = πr2 = π(0.75)2 

The angle between perpendicular to the loop and the magnetic field is 30°.
