Question

the matter dipole moment of a current carrying coil does not depend upon ::-
a.number of turns of the coil
b.cross sectional area of the coil c.current flowing in the coil
d. material of the terms of the coil​

Answer 1

Answer:

nice question man best one ever

Answer 2

The matter dipole moment does not depend upon (D) material of the terms of the coil

Explanation:

• A current carrying circular circular coils behaves as a bar magnet whose magnetic moment is M=NiA ; where N=number of turns in the coil, i= current through the coil and A =area of the coil.

1. For a given perimeter circular shape has maximum area hence, maximum magnetic moment.
2. For any loop or coil , B at centre due to current in loop and M are always parallel.
