A solenoid with 1200 turns per meter has a diameter of 2.00 cm. A current I = 2.40 A flows in the counterclockwise direction in the solenoid. A rectangular loop of length L = 16.0 cm, width w = 12.5 cm, and 2 turns is centered on the axis of the solenoid.  (a) Find the magnitude of the magnetic flux through the loop.  (b) When the current is increased to 5.58 A, the magnitude of the induced emf in the rectangular loop is 116 mV. How long did it take for the current to get to this value?

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.
