Problem

A charged particle going around in a circle can be considered to be a current loop. A particle of mass

m

carrying charge

q

is moving in a plane with speed

v

under the influence of magnetic field

\vec{B}

. The magnetic moment of this moving particle: a.

\frac{mv^2 B}{2B^2}

-\frac{mv^2 B}{2\pi B^2}

-\frac{mv^2 B}{B^2}

-\frac{mv^2 B}{2B^2}
