Question

State Biot-savart's law and derive expression for
magnetic field induction at a point on the axis of a
circular current carrying wire. long answer type question answer please it's errgant​

Answer 1

Answer:

According to Biot-savart's law, the current carrying wire generates magnetic field which is directly proportional to the strength of the current (i), length of the element (dl), angle between the element and the line joining the element and the point. ... At the centre of the coil, the field will be uniform.

A current carrying wire generates a magnetic field. According to Biot-Savart’s law, the magnetic field at a point due to an element of a conductor carrying current is,

Directly proportional to the strength of the current, i

Directly proportional to the length of the element, dl

Directly proportional to the Sine of the angle θ between the element and the line joining the element to the point and

Inversely proportional to the square of the distance r between the element and the point.

Thus, the magnetic field at O is dB, such that,

Then,

where,

is the proportionality constant and

is called the permeability of free space.

Then,

In vector form,
