Question

A long solenoid has 100 turns/cm and carries current *i*. An electron moves within the solenoid in a circle of radius 3.24 cm perpendicular to the solenoid axis. The speed of the electron is 0.0469*c* (*c* = speed of light, equal to 2.998 × 10^{8} m/s). Find the current *i* in the solenoid.

Step 1

Magnetic field in the solenoid is given by :

Step 2

We know that, force on the moving electron in a magnetic field will be:

Step 3

Now, the magnetic force will be equal to the centripetal f...
