Question

A helium nucleus is completing one round of a circle of radius 0.8 m in 2 seconds. Find the magnetic field induction at the centre of the circle

Answer 1

Given that radius = 0.8 and Time = 2 sec. B = µ0/4π x 2Πi/r =10^-19.

Electric fields and magnetic fields might seem differ however they are actually part of single large force known as electromagnetic force.

Charges which are not moving seem to produce electric fields. But when those charges tend to move, they instead seem to create magnetic fields.
