# $EMF$ Coil into Field

APPHEM-VBNVUC

What average $EMF$ would be produced from moving the coil, of one loop with a radius of $0.4 \text{ m}$, perpendicularly into the uniform magnetic field of $0.5 \text{ T}$? It takes 1 second from when the loop first reaches the edge of the magnetic field, until it is completely in the magnetic field.

A

$-0.02 \pi \text{ volts}$

B

$- 0.08 \pi \text{ volts}$

C

$-0.12 \pi \text{ volts}$

D

$-0.8 pi \text{ volts}$

E

$-1.2 \pi \text{ volts}$
