The area A of an 120turn current loop that produces a magnet

The area, A, of an 120-turn current loop that produces a magnetic moment, M=2A-m² with a current I = 10-A is _____ cm²

Solution

Magnetic Moment M= NIA

N is the number of turns=120

A is the Area

I is the current = 10 Amphere.

M= 2,

M=NIA= 120*10*A= 2

1200*A=2

A=1/600

=.0017 m²

=17 cm²
