Question:

A thin copper bar of length ℓ = 10.0 cm is supported horizontally by two (nonmagnetic) contacts. The bar carries current I1 = 100 A in the -x direction, as shown in Figure P30.52. At a distance h = 0.500 cm below one end of the bar, a long straight wire carries a current I2 = 200 A in the z direction. Determine the magnetic force exerted on the bar.
