Which of the following is/are the properties of magnetic field lines?

The best material to make permanent magnets is

Two magnetic field lines can never ever intersect.

A magnet always has _____ poles.

 The surest test for magnetism is a test for repulsion.

The geometrical length of a bar magnet is $7 \mathrm{cm}$. Its magnetic length will be _____ $\mathrm{cm}$. (Write the answer in upto three decmial points)

Inside a bar magnet, the magnetic field lines

The net magnetic flux through any closed surface, kept in a magnetic field is

$\oint \overrightarrow{B}·d\overrightarrow{s}=0$ equation is not according to the following

Gauss law for magnetism states that the magnetic flux through any closed surface is equal to the magnetic charge enclosed by the surface divided by permeability.
