Question

In the presence of a magnetic field with a strength of 6.0x10^-3T, a 36m long wire carries a

current of 11.0A. Determine the amount of the magnetic force acting on the wire. The angle of

the line is 45 degrees

Answer 1

$$F=BIl\sin\theta\\ =6.0*10^{-3}*11.0*36*\sin45^\circ=1.6\:\rm N$$
