Question
In the figure below, the cube is 40.8 cm on each edge. Four straight segments of wire?ab, bc, cd, and da?form a closed loop that carries a current I = 4.60 A in the direction shown. A uniform magnetic field of magnitude B = 0.023 T is in the positive y direction. Determine the magnetic force on each segment. (a) ab F = ________mN (b) bc F = ________mN (c) cd F =________ mN (d) da F = ________mN (e) Explain how you could find the force exerted on the fourth of these segments from the forces on the other three, without further calculation involving the magnetic field.
Explanation / Answer
F=i l cross b a)ab F=0 b)bc F=4.6*40.8*0.023 c)cd F=4.6*40.8*0.023 component of l in direction perpendicular to i d)daF =4.6*40.8*sqrt(2)*0.023
