pls answer in copy ...
Answers
Answer:
A solenoid is a type of electromagnet, the purpose of which is to generate a controlled magnetic field through a coil wound into a tightly packed helix. The coil can be arranged to produce a uniform magnetic field in a volume of space when an electric current is passed through it.
Explanation:
A solenoid is a very important coil of wire that is used in inductors, electromagnets, antennas, valves, and many more. The application of a solenoid varies in many different types of industries. It can be used in a simple locking device, medical clamping equipment, an automotive gear box, and an air conditioning unit.

A coil with many circular close turns of insulated copper wire (like a cylinder as shown above) is a solenoid.
One end of such a solenoid behaves like the north pole and the other as a south pole.
Therefore magnetic field due to current in the solenoid is similar to a bar magnet. The fields always emerge out of the North pole and always merge into the South pole
The field inside the solenoid is uniform.

The strong magnetic field inside the solenoid is so strong that it can be used to magnetize a piece of soft iron when it is placed inside the coil. The magnet formed like this is called a Electromagnet
