Question:

A long, straight wire with a linear mass density of $50 \mathrm{~g} / \mathrm{m}$ is suspended by threads, as shown in Figure P24.58. There is a uniform magnetic field pointing vertically downward. A $10 \mathrm{~A}$ current in the wire experiences a horizontal magnetic force that deflects it to an equilibrium angle of $10^{\circ}$. What is the strength of the magnetic field $\vec{B}$ ? image text in transcribed
