If magnetism monopoles existed, then the Gauss`s law of magnetism can be modified as:

Divergence of B will be proportional to the magnetic charge density.

Mathematically Gauss`s law of magnetism can be witten as

$\mathrm{\nabla}.B={\mu}_{0}{\rho}_{m}$

Which of the following correctly describes the magnetic field near a long straight wire?

A. The field consists of straight lines perpendicular to the wire

B. The field consists of straight lines parallel to the wire

What is a compass? How is a compass used to find directions?

Magnetic field lines never intersect each other because

There will be two directions of the field at the same point.

Feild lines repel each other

Field lines follow discrete paths only

If field lines intersect they create a new magnetic field within the existing fieldTwo parallel wires carry currents of 20 A and 40 A in opposite directions. Another wire carrying a current antiparallel to 20 A is placed midway between the two wires. The magnetic force on it will be
