A straight wire carries a current of 40 A in a uniform field whose magnitude is 80 mT. If the force per unit length on this wire is 2.0 N / m, determine the angle between the wire and the magnetic field.

A long, straight wire carrying a current of 296 A is placed in a uniform magnetic field that has a magnitude of 6.21 × 10-3 T. The wire is perpendicular to the field. Find a point in space where the net magnetic field is zero. Locate this point by specifying its perpendicular distance from the wire.
