WAEC - Physics (1997 - No. 28)
The relationship between the directions of magnetic field, the current-carrying wire in the field is easily remembered using
Octet rule
Right hand grip rule
Maxwell’s screw rule
Ampere’s swimming rule
Fleming’s left hand rule
Wyjaśnienie
The Right Hand Grip Rule (or Right Hand Rule) is used to determine the direction of the magnetic field around a current-carrying conductor. If you grip the wire with your right hand such that your thumb points in the direction of the current, your fingers will curl in the direction of the magnetic field lines.
