how to identify the direction of magnetic field lines in circular loop when current passed through it using RIGHT HAND THUMB RULE.

Open in App

Solution

To find the direction of Field using Right hand Thumb Rule
Point the thumb in direction of motion of Conductor
Finger in the direction of Current then Second finger represents the Direction of Field.

In straight current carrying wire if Current is upward direction then Field will be in Anticlockwise direction and viceversa.
