6: A single-turn circular loop of wire rests flat on this page.
A magnetic field is directed perpendicular to this page pointing
outwards (towards you). When the magnetic field strength increases
from 3.2 T to 6.5 T in 0.026 seconds, a 1 V emf is induced in the
coil.
a) Calculate the radius of the loop.
b) State the direction of the induced current and briefly
explain how you arrived at your answer.
