When an electric current flows out of the page, what is the direction of the magnetic field?

(a) Clockwise

(b) Anti-clockwise

(d) Parallel to the current

I had been asked this question in an online interview.

My question comes from Magnetomotive Force and Magnetic Field Strength in chapter Simple Magnetic Circuits of Basic Electrical Engineering

Best answer
The correct option is (b) Anti-clockwise

The best explanation: When the current flows out of the page, the magnetic field is anti-clockwise because of the right hand thumb rule, we orient our thumb out of the page and our fingers curl in the anti-clockwise direction.
