Question

A coil of area A No.of turns N carries current I then magnetic moment will be​

Answer 1

Answer:

Magnetic moment (M)= NIA

Explanation:

Here the area A vector will be normal to the plane of the coil. SI units for M are Ampere square meter (Am²)

Answer 2

Answer:

Magnetic moment, $M=NIA$

Explanation:

Let the area of the coil is A. It has N number of turns. It carries a current I. The magnetic moment is equal to the magnetic dipole moment of the system. It is equal to the product of area of cross section and the current flowing through the coil. Its formula is given by :

$M=NIA$

Its SI unit is Ampere-square meter or $A-m^2$

Hence, this is the required solution.
