Right-Hand Curl Rule (RHCR)

Definition

The Right-Hand Curl Rule is a method used to determine the direction of the magnetic field around a current-carrying wire or a loop. It states that if you point your right thumb in the direction of the current, then the curling fingers will indicate the direction of the magnetic field.
