Around any magnets there is a region within which the magnet has an influence.
This region is known as the magnetic field.
05. Draw the magnetic field of the permanent magnets and indicate the direction of the
magnetic field with an arrowhead.
When an electric current flows through an electric conductor a magnetic field is
created in the around of the conductor
, 06. To observe a magnetic field effect due to straight conductor carrying a current is
given below. In this setup observe the deflection of the compass in different
situations and state.

Direction of the magnetic field due to a current flowing through a straight
conductor
There are two rules that could be used to find the direction of the magnetic field
due to a current flowing through a straight conductor
