The direction of magnetic lines of force produced by passing a direct current in a straight conductor are :
Perpendicular to the conductor & coming outwards
Parallel to conductor
Surrounding the conductor and of circular nature
Perpendicular to the conductor & coming inwards
The magnetic lines of forces are produced around the conductor and are perpendicular to the direction of current.They are circular in nature.
(a) Draw a sketch to show the magnetic lines of force due to a current-carrying straight conductor.
(b) Name and state the rule to determine the direction of magnetic field around a straight current-carrying conductor.
