Question

This circle represents a wire running towards you. Using the right hand curl rule, in which direction is the magnetic field moving if the current is flowing at you?

The magnetic field is moving towards me.


The magnetic field is moving away from me.


The magnetic field is moving in a clockwise direction around the wire.


The magnetic field is moving in a counterclockwise direction around the wire.

Answer 1

The magnetic field is moving in a counterclockwise direction around the wire.

Step-by-step explanation:

The rule that specifies the direction of magnetic field around a conductor and current current flowing through a conductor is the CLENCHED FIST RULE which states that "a conductor gripped with a right hand is such that the curled finger moved clock wisely and in the direction of the magnetic field with the thumb pointing upward in the direction of the current flowing through the conductor and vice versa.

The direction of my thumb will be pointing towards me if currents flows downwards the conductor, hence the curled finger will flow in the anti clockwise direction when the current flows towards me.
