The radius of a circular conducting coil...

The radius of a circular conducting coil of 100 turns is 10 cm . If 2 A current passes through the coil , what will be the magnetic moment generated ?

Text Solution

Verified by Experts

Magnetic moment ,
`P_(m)=NIA=NIpir^(2)`
`=100xx2xx(pixx0.1xx0.1)" " [because10cm = 0.1m]`
`=6.28A.m^(2)`
