Question

A coil of 100 turns, carrying a current of \( 5 \, \text{A} \), is placed in a magnetic field of \( 2 \, \text{T} \). The area of each turn is \( 0.01 \, \text{m}^2 \). What is the magnetic moment of the coil?

• A. \( 0.5 \, \text{A} \cdot \text{m}^2 \)
• B. \( 1.0 \, \text{A} \cdot \text{m}^2 \)
• C. \( 2.0 \, \text{A} \cdot \text{m}^2 \)
• D. \( 5.0 \, \text{A} \cdot \text{m}^2 \)

Hint:

Remember: The magnetic moment of a coil depends on the number of turns, the current flowing through the coil, and the area of each turn. A higher number of turns or current increases the magnetic moment.
