Question

What is a solenoid? What does the pattern of feild lines inside the solenoid indicate ??

Answer 1

a cylindrical coil of wire acting as a magnet when carrying electric current.

Answer 2

Here is your answer-

When A copper wire with resistive coating is wound in a chain of loops, it is called solenoid.

The properties of magnetic field of a solenoid are very similar to the magnetic field produced by a bar magnet.

One of the open end of the solenoid act as a magnetic north pole and Other end act as the South Pole. The magnetic lines of force inside the solenoid are parallel to each other. This means that the intensity of magnetic field with in the solenoid is uniform everywhere.
