Question

A straight, vertical wire carries a current of 1.20 $\mathrm{A}$ downward in a region between the poles of a large superconducting electromagnet, where the magnetic field has magnitude $B=$ 0.588 $\mathrm{T}$ and is horizontal. What are the magnitude and direction of the magnetic force on a $1.00-\mathrm{cm}$ section of the wire that is in this uniform magnetic field, if the magnetic field direction is (a) east; (b) south; (c) $30.0^{\circ}$ south of west?

Step 1

Given: I = 1.20 A, B = 0.588 T, L = 0.01 m, θ = 90° Use the formula for magnetic force: F = ILBsinθ F = (1.20)(0.01)(0.588)(sin 90°) F = 7.06 x 10^-3 N Show more…
