Maximum induced emf:
Number of turns = Length/Circumference = L/(2πr) = 1.6/(2 × π × 3.2 cm(1m/100cm)) = 7.96 = 8 turns
Angular speed ω = 2πf = 2π × 93 rev/min(1min/60s) = 3.1π rad/s
A 1.6-m wire is wound into a coil with a radius of 3.2 cm.
If this coil is rotated at 93 rpm in a 7.1 × 10−2 T magnetic field, what is its maximum emf?
