The magnet can be completely demagnetized by
Breaking the magnet into small pieces
Heating it slightly
Droping it into ice cold water
A reverse field of appropriate strength

What is the difference between Gauss’s law in electrostatics and Gauss’s law in magnetism ?
A short magnet of moment $6.75\, Am^2$ produces a neutral point on its axis. If horizontal component of earth's magnetic field is $5 \times {10^{ – 5}}\,Wb/{m^2}$, then the distance of the neutral point should be…..$cm$
Give some of the commonly known ideas regarding magnetism.
A bar magnet is placed north-south with its north pole due north. The points of zero magnetic field will be in which direction from the centre of the magnet
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
