Define magnetic field half way between axis and outside edge, Physics

Assignment Help:

A copper rod which is 1 centimetre in diameter carries a current of 5 amps. The current is distributed uniformly throughout the rod. The magnetic field half way between the axis of the rod and its outside edge is:

a) Zero.

b) Pointing radially outward

c) Pointing radially inward

d) Circles the axis of the rod

Ans:

The magnetic field half way among the axis of the rod and its outside edge is circles the axis of the rod.
