Question

what is biot - savant law ? Derive an expression for magnetic field at a point on the axis of a current carrying circular coil.​

Answer 1

Use Biot-Savart law to derive theexpression for the magnetic fieldon the axis of a current carryingcircular loop of radius R. Draw themagnetic field lines due to acircular wire carrying current I. According to the Biot-Savart law, ... Give the magnitude and direction of B at a point 2.5 m east of the wire.

Answer 2

Answer:

We have been asked in the question to give an expression of the magnetic field on the axis of a circular current-carrying loop which we can find using the Biot-Savart law. The expression is, B=μ0IR22(R2+x2)3/2, where R is the radius of the loop, I is the current flowing through it and x is the distance from the loop.
