University Physics II · Faraday induction and inductance
A decreasing outward field
Problem
A square loop of side $0.20\,\mathrm m$ lies in a magnetic field directed out of the page. The field decreases uniformly at $0.40\,\mathrm{T\,s^{-1}}$. Find the emf magnitude and induced-current direction.
Hint
The loop area is the square of its side.
