Can a current carrying circular loop act as a magnetic dipole? Give the expression for the magnetic field at a point, due to a current carrying circular loop.

Explanation

Yes. `" "B=(mu_(@)/(4pi))(2m)/x^(3)`
where, m = magnetic moment of the current loop
`" "m=IA`
`" "I=` current,
`" "A=` area of circular loop,
`" "x=` distance of the point on the axis of the coil.
