The work done by a uniform magnetic field on a moving charge is,

A conducting circular loop of radius $r$ carries a constant current $i.$ It is placed in a uniform magnetic field ${\overrightarrow{B}}_0$ such that ${\overrightarrow{B}}_0$ is perpendicular to the plane of the loop. The magnetic force acting on the loop is

The magnetic field at a distance $r$ from a long wire carrying current $i$ is $0.4 \mathrm{T}$. The magnetic field at a distance $2r$

Find the magnetic field at $P$ due to the arrangement as shown.

A current-carrying coil is subjected to a uniform magnetic field. The coil will orient so that its plane becomes

A bar magnet of magnetic moment $M$, is placed in a magnetic field of induction $B$. The torque exerted on it is

A steel wire of length $l$ has a magnetic moment $M$. It is then bent into a semicircular arc. The new magnetic moment is

A millivoltmeter of $25 \mathrm{mV}$ range is to be converted into an ammeter of $25 \mathrm{A}$ range. The value (in ohm) of necessary shunt will be
