- When a circular loop is associated with the current I, it starts to act as a magnet and its magnetic moment is find as given below.
- Magnetic moment (μ): The magnetic strength and orientation of a magnet or other object that produces a magnetic field.
- It is a vector quantity associated with the magnetic properties of electric current loops.
- It is equal to the amount of current flowing through the loop multiplied by the area encompassed by the loop.
μ = N i A
where μ is the magnetic moment, A is the area of the coil, N is no. of turns and I is current in the coil.
- Its direction is established by the right-hand rule for rotations.
EXPLANATION:
The Magnetic moment μ = N i A is independent of the magnetic field in which it is lying.
- As there is no magnetic field component in the formula.
- So the correct answer is option 1.
