Question

Four similar magnets of moments M each form a square with unlike poles at the corners the resultant magnetic moment is

Answer 1

Answer:

net magnetic moment of the system of four magnets must be ZERO

Explanation:

All four magnets are connected in such a way that they forms a square and at the junction they are connected with opposite poles

So here we know that magnetic moment is a vector quantity and when two magnets of opposite direction magnetic moment is added vectorialy then it will give ZERO resultant

Here when we form a square using the magnets then opposite sides of the magnet will cancel out each other

and hence net magnetic moment of the system of four magnets must be ZERO
