A wire carries a current of 10 A in the +x-direction.
(a) Find the force per unit length on the wire if it is in a magnetic field that has components of Bx = 0.020 T, By = 0.040 T, and Bz = 0 T.
(b) Find the force per unit length on the wire if only the field’s x-component is changed to Bx = 0.050 T.
(c) Find the force per unit length on the wire if only the field’s y-component is changed to By = – 0.050T.
