The magnetic moment has dimensions of
Updated On: Jun 20, 2022
- $[LA]$
- $ [L^2 \, A ] $
- $ [ LT^{ - 1} \, A ] $
- $ [ L^2 T^{ - 1} \, A ] $
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Magnetic moment of a current carrying coil is defined as the product of current in the coil with the area of coil in vector form.
That is, $\vec{M}=I \vec{A}$
Thus, dimensions of $M =[ A ]\left[ L ^{2}\right]$
$=\left[ L ^{2} A \right]$
That is, $\vec{M}=I \vec{A}$
Thus, dimensions of $M =[ A ]\left[ L ^{2}\right]$
$=\left[ L ^{2} A \right]$

Physical World
The physical world includes the complications of the natural world around us. It is a type of analysis of the physical world around us to understand how it works. The fundamental forces that control nature are:
- Gravitational Force is a universal force that exists as an outcome of mutual attraction between any two objects with respect to their masses.
- Electromagnetic Force can be understood as the force that is present between the charged particles. The force is stated by Coulomb’s law.
- Strong Nuclear Force is the force that ties the protons and neutrons in a nucleus. Of all the elemental forces in nature, a strong nuclear force is the strongest as its name suggests.
- Weak Nuclear Force can only be noticed in some of the nuclear processes such as the beta decay of the nucleus.
