Question

The resultant magnetic moment due to two current carrying coil of radius r ,making an angle of 60° with each other will be ?????????

Answer 1

Explanation:

Magnetic moment of coil-1 μ

1

=iπr

2

Magnetic moment of coil-2 μ

2

=iπr

2

μ

1

⊥μ

2

∴ resultant of μ

1

and μ

2

is μ=

(μ

1

2

+μ

2

2

)

=

2

μ

1

=

2

iπr

2....

hope this will help us

..

thank you
