12. A segment of wire (which is part of a complete circuit) is on a spacecraft traveling to Jupiter. The net gravitational force on the wire segment is zero. The wire carries a current of 15.0 A and stretches 25.0 cm. Take the position of the wire from x = 0.0 cm to x = 25.0 cm. A magnetic field of varying magnitude is present in the y direction and varies as a function of the x position as B = 2.0x10* x T. a. What is the net force on the wire due to the magnetic field? b. If the wire is clamped at one end, x = 0.0 cm with the other end free to move, is there a torque on the wire due to the magnetic field? Explain.
