Explanation:
Particles in solids are always vibrating (moving back and forth) in place.
Information provided:
Length of wire, L = 320 m
Current through the wire, I = 120 Amps
Earth's magnetic field acting on the wire, B = 5.0*10^-5 T
Angle at which the magnetic field acts, Ф = 60°
By definition;
Force on the wire, F = LBI Sin Ф
Substituting;
F = 320*5*10^-5*120*Sin 60 = 1.663 N
