KCET2009PhysicsMagnetic Effects of Current
The magnetic dipole moment of a current loop is independent of
Options
- Amagnetic field in which it is lying
- Bnumber of turns
- Carea of the loop
- Dcurrent in the loop
Correct answer
A. magnetic field in which it is lying
Step-by-step solution
Magnetic dipole moment of a current is given by M = NIA where N = number of turns I= current in a loop A = area of the loop From the above relation it is clear that magnetic dipole moment of a current loop is independent of the magnetic field in which it is lying.
