Electric current effect on magnetism

Question

Above there is a circular loop if wire that has a counter clockwise current running through it. What is the direction of the magnetic field inside of the loop.

Answer 1

Using right hand thumb rule, the direction of magnetic field lines due the current in circular is shown in the figure.

Thus the magnetic field at any point P inside the loop points into the screen whereas at any point q outside the loop points out of the screen.
