In two separate experiments the neutral points due to two small magnets are at a distance of $r$ and $ 2r$ n broad side-on position. The ratio of their magnetic moments will be
$4:1$
$1:2$
$2:1$
$1:8$
State the direction of magnetic dipole moment (From $\mathrm{S}$ to $\mathrm{N}$ pole of magnet). and Write the unit of magnetic dipole moment.
Show the magnetic field of bar magnet in a panoramic way.
Magnetic dipole moment is a
Two points $A$ and $B$ are situated at a distance $x$ and $2x$ respectively from the nearer pole of a magnet $2\,cm$ long. The ratio of magnetic field at $A$ and $B$ is
Two similar bar magnets $P $ and $Q$ , each of magnetic moment $M,$ are taken, If $P$ is cut along its axial line and $Q$ is cut along its equatorial line, all the four pieces obtained have
