A circular loop of radius 5.0 cm and resistance 0.20 Ω is placed in a uniform magnetic field perpendicular to the plane of the coil. The magnitude of the field changes with time according to B(t) = 0.50e−0.20t T, in which t is in seconds. What is the magnitude of the current induced in the coil at the time t = 2.0 s?

A toroidal solenoid has a central radius of 0.50 m and a cross-sectional diameter of 10 cm. When a current passes through the coil of the solenoid, the magnetic field inside the solenoid at its center has magnitude 2.0 μT. What is the smallest value of the magnetic field inside the solenoid when this current is flowing?

An ideal solenoid having 250 turns, length 0.230 m, and radius 6.30 cm has a downward magnetic field passing through it. If the magnetic field through the coil is decreasing at a rate of 0.187 T/s, what is the magnitude of the emf induced in the coil?
