A $10 \mathrm{~m}$ long wire carrying a current of 22 A makes an angle of $37^{\circ}$ with the Earth's magnetic field of 0.51 $\mathrm{mT}$. What is the magnetic force on the wire?
A) $0.068 \mathrm{~N}$
B) $0.011 \mathrm{~N}$
C) $0.19 \mathrm{~N}$
D) $0.090 \mathrm{~N}$
E) $0.11 \mathrm{~N}$

Quizplus · Accepted Answer

The magnetic force on the wire can be calculated using the formula $ F = I \cdot L \cdot B \cdot \sin(\theta) $. Substituting the given values: $ F = 22 \, \mathrm{A} \times 10 \, \mathrm{m} \times 0.51 \times 10^{-3} \, \mathrm{T} \times \sin(37^\circ) \approx 0.068 \, \mathrm{N} $.
