Write the Gauss’s law in equation form for electrostatics and magnetism. What is the difference between them ?
Gauss's law for electrostatic,
$\sum \overrightarrow{\mathrm{E}} \cdot \overrightarrow{\Delta \mathrm{S}}=\frac{q}{\varepsilon_{0}}$
(Where charge $q$ enclosed by a surface)
Gauss's law for magnetism,
$\sum \overrightarrow{\mathrm{B}} \cdot \overrightarrow{\Delta \mathrm{S}}=0$
The difference between the Gauss's law of magnetism and electrostatics is that isolated magnetic poles (also called monopoles) does not exist.
Two magnetic lines intersect ? Why ?
A short magnet is allowed to fall along the axis of a horizontal metallic ring. Starting from rest, the distance fallen by the magnet in one second may be.....$m$
Give the characteristics of magnetic field lines.
When the $N-$pole of a bar magnet points towards the south and $S-$pole towards the north, the null points are at the
