Question

A wire 28.0cm long lies along the z-axis and carries a current of 7.20A in the +z-direction. The magnetic field is uniform and has components Bx= -0.236T , By = -0.984T , and Bz = -0.344T .

Find the x,y and z component of the magnetic force on the wire AND What is the magnitude of the net magnetic force on the wire??.

Answer 1

A)

x-component of the magnetic force on the wire = 0.984*7.2*0.28 = 1.98 N

B)

y-component of the magnetic force on the wire = 0.236*7.2*0.28 = -0.476 N

C)

z-component of the magnetic force on the wire = 0

d) magnitude = sqrt(x^2 + y^2 +z^2) = 2.04 N
