A conducting ring of radius r having charge q is rotating with angular velocity `omega` about its axes. Find the magnetic field at the centre of the ring.

Text Solution

Verified by Experts

Current in the ring `I=(omegaq)/(2pi)`
Magnetic field `B=(mu_0I)/(2r)=(mu_0 omegaq)/((2pi)xx2r)`
` implies B=(mu_0 omegaq)/(4pir)`
