right hand thumb rule​

Answer 1

Explanation:

According to this rule, if we grasp the current-carrying wire in our right hand so that our thumb points in the direction of current, the direction in which our fingers encircle the wire will give the direction of magnetic field lines around the wire. When thumb points upwards, the curled fingers are anticlockwise.
