1. Introduction When a current-carrying rectangular loop (coil) is placed in a uniform magnetic field, it experiences a torque which tends to rotate the coil. This principle is the working basis of

Question 2

A proton is accelerated through a potential difference of 200 V. It then enters a region where there is a magnetic field B = 0.5 T. The magnetic field is perpendicular to the direction of motion of th
