Final answer:
Right Hand Rule 2 (RHR-2) is used to determine the direction of the magnetic field induced by a current-carrying wire. It states that you can point the thumb of your right hand in the direction of the current, and the fingers will curl in the direction of the magnetic field loops.
Step-by-step explanation:
Right Hand Rule 2 (RHR-2) is a rule used to determine the direction of the magnetic field induced by a current-carrying wire. According to RHR-2, you can point the thumb of your right hand in the direction of the current, and the fingers will curl in the direction of the magnetic field loops created by it.
This rule is valid for any current segment and is often used to determine the direction of the magnetic field created by a long straight current-carrying wire or a loop of wire.
For example, if you have a wire with current flowing from left to right, you can use RHR-2 to determine that the magnetic field created around the wire will have clockwise loops when viewed from above.
