A long, straight wire with linear mass density of 50g/m is
suspended by threads, as shown in the figure . There is a uniform
magnetic field pointing vertically downward. A 13A current in the
wire experiences a horizontal magnetic force that deflects it to an
equilibrium angle of 10 degrees. What is the strength of the
magnetic field B?

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?.
