What is the unit of magnetic moment of a current carrying a closed loop?
Answers
Magnetic dipole moments have dimensions of current times area or energy divided by magnetic flux density. In the metre–kilogram– second–ampere and SI systems, the specific unit for dipole moment is ampere-square metre.
Answer:
The magnetic moment is the magnet's strength. Its SI units are amp*
Explanation:
The magnetic dipole moment of the current loop equals the product of ampere-turns and current loop area. M represents it.
The magnetic dipole moment of the current loop equals the product of ampere-turns and current loop area. M represents it.
M = nIA
Where n =represents the number of turns in a circular current loop.
I = current through the loop.
A = area of each turn of the loop.
Magnetic dipole moment is measured as a vector quantity. Its direction is perpendicular to the plane of the loop and is directed outwards for anticlockwise current in the loop and inwards for clockwise current in the loop.
