Question

In Magnetic Induction At A Point Due to Straight Conductor carrying current

then How B inversely to 1/a​

Answer 1

Answer:

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

Answer 2

Answer:

ANSWER

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.
