1.	Deduce the expression for the magnetic field induction at the centre of a circular electron orbit of radius r, and angular velocity of orbiting electron `omega`.
Answer» The electron moving on a circular orbit acts like a current loop. Magnetic field induction in magnitude, at the centre of the current loop is `B=(mu_0)/(4pi i)(2pir)/(r)=(mu_02pi)/(4pir)(e/T)=(mu_0)/(2r)((e)/(2pi//omega))=(mu_0eomega)/(4pir)`
