Moving Charges And Magnetism

A particle having a charge \(100 \mathrm{e}\) is revolving in a circular path of radius \(0.8 \mathrm{~m}\) with 1. r.p.s The magnetic field produced at the centre of the circle in SI unit is \(\left(\mu_0=\right.\) permeability of vacuum, \(e= \left.1.6 \times 10^{-19} \mathrm{C}\right)\)
