A very long solenoid is connected to a battery via a switch as shown. Loops A and B have the same diameter and are inside the solenoid as shown. Loops C and D surround the solenoid. All of the loops are conducting and have a single turn.  The solenoid consists of 600 turns per centimeter and has a radius of 0.10 m. Loop B is 0.040 m in radius. The plane of loop B is at 50o with respect to the axis of the solenoid. When the switch is closed, the current in the solenoid increases uniformly from zero to 0.045 A in 0.0020 s. What is the magnitude of the induced emf in loop C (radius ?? = 0.15 ?)? Show your work.

Electromagnets

The word "electromagnet" is composed of two words, ‘electro’ and ‘magnet’. It is a type of magnet in which an electric current helps in the generation of a magnetic field. Electromagnets usually consist of two major parts, wire and a coil around which the wire is wound. This is called a solenoid. When an electric current is allowed to pass through the coiled wire, the electric current produces a magnetic field. This magnetic field is present only when current is passing through the wire.
