A circular loop made from a flexible conducting wire is, Ask an Expert

Academics

A circular loop made from a flexible, conducting wire is shrinking. Its radius as a function of time is r = r₀e^βt, where r₀ = 5.40 cm and β = 0.700 s^-1. The loop is perpendicular to a steady, uniform magnetic field B = 0.600 T.

What is the induced emf in the loop at t = 3.00 s?
