A 1.7-m-long wire carries a current of 6.3 a and is, Ask an Expert

Academics

A 1.7-m-long wire carries a current of 6.3 A and is immersed within a uniform magnetic field B. When this wire lies along the +x axis [i.e., the current is directed in the +x direction], a magnetic force F = - 3.2j N acts on the wire, and when it lies along the +y axis [i.e., the current is directed in the +y direction], the force is F = (3.2i - 4.7k) N. Find B.
