Question 1

Consider a circular loop of wire lying in the plane of the table. Let the current pass through the loop clockwise. Apply the right-hand rule to find out the direction of the magnetic field inside and outside the loop.

Answer

Direction of magnetic field:
Inside the loop — Going into the table.
Outside the loop — Emerging out of the table.

Consider a circular loop of wire lying in the plane of a table. Let the current pass through the loop clockwise. Applying the right hand rule, find out the direction of the magnetic field inside and outside the loop. NCERT Class 10 Science CBSE Solutions.

Explanation:
On applying the right-hand rule to the downward direction of the current flowing in the circular loop, the direction of magnetic field lines will be as if they are emerging out from the table outside the loop and merging into the table inside the loop.
Similarly, for the upward direction of the current flowing in the circular loop, the direction of magnetic field lines will be as if they are emerging out from the table outside the loop and merging into the table inside the loop.
