Question

Magnitude of magnetic field intensity at a point due to a current carrying
conductor is given by:
(a) Biot-savart law (b)Right hand thumb rule
(c)Fleming's right hand rule (d)Coulomb's law ​

Answer 1

Answer:

option (a)

Biot-Savart's law

Answer 2

The magnitude of the magnetic field at a point due to a current-carrying conductor is given by the Biot-Savart law. (Option A)

• According to the Biot - Savart law, the magnetic field produced by a small current element is linearly dependent on the current element's length, the current, the sin of the angle formed by the current direction, and the line joining the current element and the point, and inversely related to the square of the distance between the current element.
• The magnetic field is directly dependent on the current in the conductor.
