Question

(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.

Answer 1

Explanation:

(a) According to a current-carrying straight conductor, the magnetic field lines are distorted circles whose centers are on the wire .

The magnetic lines of force due to a current-carrying straight conductor is shown in the attachment.

 (b) Maxwell's right-hand thumb law is used to set the direction of the magnetic field across a conductor carrying straight current.

• By this rule, if we understand a current-carrying wire in our right hand so that our thumb statements in the current's direction, the path our fingers surround the wire will give the position of magnetic field lines across the wire.
• The curled fingers are anticlockwise, when the thumb points upward. The path of the magnetic field lines is, therefore, anticlockwise.
• The curl fingers are in circular motion while thumb points downwards. The direction of that magnetic field lines is therefore in clockwise direction.
