Question

A wire carries a steady current of 2.20

a. a straight section of the wire is 0.750 m long and lies along the y axis within a uniform magnetic field, = 2.00 t. if the current is in the positive y direction, what is the magnetic force on the section of wire?

Answer 1

By definition we know that the force is the vector product of the vector of the current by the length with the magnetic field vector. The current in this case goes in a positive "Y" direction. If we assume that the magnetic field goes in the positive "K" direction, then the result will be in the positive "X" direction. Attached solution.
