# Single-turn Circular Loop#

A single-turn circular loop of wire of radius 70 $$\textrm{ mm}$$ lies in a plane perpendicular to a spatially uniform magnetic field. During a 0.2 $$\textrm{ s}$$ time interval, the magnitude of the field increases uniformly from 125 $$\textrm{ mT}$$ to 325 $$\textrm{ mT}$$.

## Part 1#

Determine the emf induced in the loop.

## Part 2#

If the magnetic field is directed out of the screen, what is the direction of the current induced in the loop?
