# EMF vs Potential difference

A circular loop of radius $$R$$ is placed in a region of uniform time varying magnetic field $$B=B_0t$$. The magnetic field is into the plane of the ring. There are two points $$A$$ and $$B$$ diametrically opposite to each other on the ring, as shown in the diagram.

What is the potential difference between points $$A$$ and $$B$$?


Details and Assumptions:

• The circular loop has uniform thickness and resistivity.
• $$B_0$$ is a constant and $$t$$ is time.
