Or
The
existence of this field can be detected by using a magnetic compass needle. The
direction of magnetic field is predicted by using Maxwell's right-hand thumb
rule.
It
states that, if you hold a current-carrying conductor in right-hand, such that,
the thumb points in the direction of electric current, then the direction in
which fingers encircle, gives the direction of magnetic field.
The
uniform and non-uniform magnetic fields are shown in the diagram below (1)
Denser
the field lines, stronger is the magnetic field in that region.
