Force on a Current Loop in a Nonuni form Magnetic Field. It was shown in section 27.7 that the net force on a current loop in a uniform magnetic field is zero. But what if B^→ is not uniform? The figure shows a square loop of wire that lies in the wy-plane. The loop has corners at (0, 0), (0, L),(L, 0), and (L, L) and carries a constant current / in the clockwise direction. The loop is in a magnetic field that points into the page and whose magnitude is given by the equation: B = (B_oxy/ L²) where B_o is n positive constant.

(a) Find an equation for the magnitude of the net magnetic force on the loop in terms of the constants B_o, I, and L.

(b) Find an equation for the direction of the net magnetic force on the loop in terms of the constants B_o, I, and L.

(c) What is the magnitude and direction of the net magnetic force on the loop for L = 25 mm I = 2.5 A wnrl B = 0.75 T?
