Biot Savart law was given by Biot and Savart after doing many experiments. This law is related with the magnetic field induced at a point due to a small current carrying element (conductor). According to the law the magnetic field induced at a point near the current carrying element is directly proportional to the current flowing in conductor, length of the element, sin `theta` and inversely proportional to the square of the distance of point from the element.

As the distance between the point and current carrying element decreases, dB:

A

Increases

B

Decreases

C

Remains same

D

Both (a) and (b)
