A 40-Turn Circular Coil (Radius = 4 $\Omega$ )Is Placed in a Uniform Magnetic Field Directed Perpendicular to 0.20

Multiple Choice

A 40-turn circular coil (radius = 4.0 cm,total resistance = 0.20 $\Omega$ ) is placed in a uniform magnetic field directed perpendicular to the plane of the coil.The magnitude of the magnetic field varies with time as given by B = 50 sin(10 $\pi$ t) mT where t is measured in s.What is the magnitude of the induced current in the coil at 0.10 s?

A) 50 mA
B) 1.6 A
C) 0.32 A
D) zero
E) 0.80 A
