Question

Magnetic field due to current through a Circular loop ​

Answer 1

Answer:

A 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.

Answer 2

Answer:

$\huge{\mathcal{\green{A}\pink{N}\purple{S}\pink{W}\purple{E}\pink{R}\purple{:}\pink{:}}}$

The magnetic field strength at the center of a circular loop is given by B=μ0I2R(at center of loop), where R is the radius of the loop. RHR-2 gives the direction of the field about the loop
