Rules for determining the direction of the lines of force

Rules for determining the direction of the lines of force.

Answers

1. Right-hand screw rule
This rule states that “if a right-hand screw advances in the direction of the current, then the rotation of the screw is in the direction of the field”.

2. Right-hand grip rule
States that “if the wire carrying a current is gripped with the right hand, using the thumb along the conductor and pointing in the direction of the current, then the direction of curled fingers is in the direction of the lines of force”.
