Question

how will be the magnetic field in a circular loop​

Answer 1

Answer:

Magnetic Field of Current Loop

Electric current in a circular loop creates a magnetic field which is more concentrated in the center of the loop than outside the loop. Stacking multiple loops concentrates the field even more into what is called a solenoid.

Answer 2

Answer:

Magnetic field is produced by an electric current flowing through a circular coil of wire . Each small section of current carrying wire contributes to magnetic field lines. At the centre of circular wire,field lines become straight and perpendicular to the plane of coil.
