Question

3. Find the force between two magnetic poles of pole strengths 40
Am and 10 Am which are separated by a distance of 20 cm in
air. Calculate the force when the distance is reduced to 10 cm.​

Answer 1

Answer: This may help you

Explanation:

Two magnetic poles of the same length attract each other with a force of 2N when placed on the two corners of an equilateral triangle. If a south pole of the same strength is placed at the third vertex, it experiences a force of magnitude.
