Question MCQ▾

The vector potential for an almost point like magnetic dipole located at the origin is

where denote the spherical polar coordinates and is the unit vector

along . A particle of mass m and charge q, moving in the equatorial plane of the dipole, starts at time with an initial speed and an impact parameter b. Its instantaneous speed at the point of closest approach is A static magnetic field does not alter the magnitude of speed of a charged particle. It only alters the direction of motion. Hence, its speed will be the same as the one it started with
