A 50-turn circular coil (radius r = 15 cm) with a total resistance R = 4.0 Ω is placed in a magnetic field directed perpendicular to the plane of the coil. The magnitude of this field varies with time as B = A sin(ωt), where A = 80 δT and ω = 50π rad/s. a) Find the electric flux through the coils at time t = 20 ms. b) Find the induced emf in the coils at time t = 20 ms. c) What is the magnitude of the current induced in the coil at time t = 20 ms?

A circular coil of 15 turns of radius 10 cm was placed in a uniform magnetic field. This coil is placed in the magnetic field at an angle of 30 degrees with the surface normal. As the magnetic flux density B increases from 1 T to 5 T within 10 seconds, calculate the induced voltage in the coil. Also, show the direction of the current flowing through the coil as B decreases in the direction shown.
