A straight copper wire lies along the x-axis and has current of I = 14.5 A running through it in the +x-direction. The wire is in the presence of a uniform magnetic field, perpendicular to the current. There is a magnetic force per unit length on the wire of 0.130 N/m in the −y-direction. (a) What is the magnitude of the magnetic field (in mT) in the region through which the current passes? mT (b) What is the direction of...

The size of the magnetic force on a straight wire of length
L carrying current I in a uniform magnetic field
with strength B is
F=ILBsin(?).
Here ? is the angle between the direction of the
current (along the wire) and the direction of the magnetic field.
Hence Bsin(?) refers to the component of the
magnetic field that is perpendicular to the wire, B?. Thus
this equation can also be written as
F=ILB?.
