Question

describe magnetic field in circular loop wire​

Answer 1

ANSWER:

Magnetic Field Due to Flow of Current through a Circular Loop:

The magnetic field produced in a circular current carrying conductor is the same as that of the magnetic field due to a straight current carrying conductor and the current carrying circular loop will behave like a magnet.

Magnetic Field due to flow of current in a Solenoid:

A solenoid is a tightly wound helical coil of wire whose diameter is small compared to its length.

Magnetic field produced by the current carrying solenoid is similar to a bar magnet. One end of a solenoid behaves as a south pole and the other end behaves as a north pole. The magnetic field produced inside a solenoid are parallel which is similar to a bar magnet.
