Magnetic Properties of Matter: Practice Problem & Solution
If number of turn, area and current through it is given by $n$, $A$ and $i$ respectively then its magnetic moment will be: (2001)
Solution Explained:
To solve this problem, we apply the core principles of Magnetic Properties of Matter. Understanding the underlying formula is key to arriving at the correct answer below:
Magnetic dipole moment of a current-carrying coil is the product of number of turns, current, and area, i.e., $M = niA$.
