Answer 1

The correct option is C Points out to the page

Given :

A loop of wire carries a current in counter clockwise direction

Solution:

According to right hand thumb rule,

If we curl the palm of our right hand around the circular wire with the fingers pointing in the direction of the current, then the extended thumb gives the direction of the magnetic field

Hence the direction of the magnetic field points into the page

The correct option is : C
