Arrive at the expression for the magnetic field at the centre of the circular path due to an orbiting electron.

Text Solution

Verified by Experts

We know that the magnetic field at the centre `(mu_(0))/(4pi).(2pii)/(r)`
i.e., `B=((mu_(0))/(4pi))((2pi)/(r))((ev)/(cancel(2pir)))`
or `B=((mu_(0)ev)/(4pir^(2)))` tesla.
