Determine the magnitude and direction of the magnetic force exerted on this wire, the orientation of the wire and hence the current is as follows. horizontally toward the south magnitude 1.44 east at horizontal what angle must the magnetic force make with the magnetic field? wnth the current? measured below the direction (b) horizontally toward the west south at 90 what angle must the magnetic force make with the magnetic field? with the current" measured below the horizontal My Notes o Ask Your Teacher 6228 037 Previous Answers osCoPhys201 What is the direction of the magnetic force on the current in each of the six cases shown below? d the web and Windows 3/16/2017Explanation / Answer
Here
B = 5.9 *10^-5 T
theta = 68 degree
L = 220 m
I = 120 A
a) for the current in the south
F = iL X B
F = 5.9 *10^-5 * 220 * 120 * sin(68)
F = 1.44 N
the direction of east at 0 degree below horizontal
b) for the current in the west direction
F = iL X B
F = 5.9 *10^-5 * 220 * 120
F = 1.56 N
the direction of south at 22 degree degree below horizontal
