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.

A 2.4 Henry inductor is connected in series with a 12.0 Volt direct current battery, a 6.0 Ohm resistor, and a switch. The switch is open so no current is flowing in the circuit. Explain what happens to the current once the switch is closed. Intelligently use "Faraday's law" and "Lenz's law" and "time constant" in your explanation. Describe what a graph of current versus time would look like, what it's value would be at time = 0, and what its value would be after a very long time.
