Question

A current carrying circular loop of wire lies flat on a table top. When viewed from above, the current moves around the loop in a counterclockwise sense. What is the direction of the magnetic field caused by this current, inside the loop? The magnetic field A) circles the loop in a counterclockwise direction. B) points straight up. C) points straight down. D) circles the loop in a clockwise direction. E) points toward the east.

Answer 1

Answer:

Option (b)

Explanation:

Maxwell right hand thumb rule: if we hold a current carrying conductor in our right hand such taht the thumb indicates the direction of current then the curling of fingers give the direction of magnetic field around the conductor and vice versa.

Here the current is counterclockwise so by use of Maxwell right hand thumb rule the direction of magnetic field is straight up.
