@@00.. |. I 2. Force on a Currrent Carrying Wire. A wire carrying 5.0A lies on a horizontal surface in the xy-plane. One end of the wire is at the origin (Orn,On,0m) and the other is at (3m.4m,0m)). The wire follows an erratic path from one end to the other. A magnetic field is present and of magnitude 0.4T directed vertically downward (B--Bk--04kT). What magnetic force acts on the wire? lHint: Break the path into tiny steps de to the right (eastward) and dy northward, such that di. -(3.0i +4.0j+0.0k)m.) (8 points)

Explanation / Answer

We know magnitude of magnetic force is given as

F=ILB sin heta

F=0.4*5*(3i +4 j)

F=2*sqrt{4^2+3^2}=10 N
