Question

The current is flowing in the wire, creating a magnetic field around itself in the direction as shown in the figure. Find out the direction of the current in the wire ?

• A. Directed to the right.
• B. Directed to the left.
• C. Equal to the magnetic field.
• D. In the same direction as the magnetic field.
• E. Zero

Answer 1

The correct option is A Directed to the right.

As per Right-hand thumb rule: Curl the fingers of your right hand around a rod carrying current in such a way that the thumb points the direction of current flow, then the curled fingers show the direction of the magnetic field.

Per the above rule, the current in question is directed from left to right.
