What Is Maxwell Right Hand Grip Rule?
Answers
The right-hand grip rule is used to determine the relationship between the current and the magnetic field based upon the rotational direction. To understand the definition, one must understand the demonstration of the right-hand grip rule. For this, the wire needs to be held in the right hand and the thumb should point towards the direction of the flow of current then curl your fingers around the wire. Now, the curled fingers show the direction of the magnetic field around the wire and how the compass would line-up if placed at that point.
Maxwell's right hand grip rule will predict the direction of force lines of the magnetic field generated by a current carrying straight conductor. This rule states that if a straight conductor carrying current is placed in the right hand in such a way that the thumb is pointing in the direction of the current, then the direction in which the fingers circle the wires provides the direction of the magnetic lines of force around the wire.
The law was sometimes called Maxwell screw law. Under this law the corkscrew travels in the direction of the current, so the hand turns in the direction of the force magnetic lines.
