A uniform magnetic field is perpendicular to the plane of a wire loop. If the loop accelerates in the direction of the field, will a current be induced in the loop? Explain why or why not.
Problem 3 Part A A copper wire with resistance 0.010 Ω is shaped into a complete circle of radius R 10 cm and placed in a long solenoid so that the axis of the solenoid and the axis of the wire loop coincide. The current in the solenoid is turned on and then slowly decreased. The magnetic field strength is initially B 0.750 T and subsequently decreases in time at the constant rate -0.035 T/s. (a) Calculate the induced emf...

An 16 cm diamter loop of wire is initially oriented perpendicular to a magnetic field 1.8 T magnetic field. The loop is rotated so that its plane is parralel to the field direction in 0.14 s. What is the average induced emf in the coil?
A loop of wire is oriented vertically, so that a vector normal to the loop is oriented to the east. An external magnetic field is directed upward. The loop begins to rotate around a vertical rotation axis. As viewed from the east, the induced current is:
