The ultimate individual unit of magnetism in any magnet is called
North pole
South pole
Dipole
Quadrupole
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
The magnetic induction in air at a distance $d$ from an isolated point pole of strength $ m$ unit will be
If a magnet of pole strength $m$ is divided into four parts such that the length and width of each part is half that of initial one, then the pole strength of each part will be
Two magnets of equal mass are joined at right angles to each other as shown the magnet $1$ has a magnetic moment $3 $ times that of magnet $2$. This arrangement is pivoted so that it is free to rotate in the horizontal plane. In equilibrium what angle will the magnet $1$ subtend with the magnetic meridian
In which direction does a free hanging magnet get stabilized ? Explain.
