1. One long straight wire carries a current of 7.5A. A 2.00m length of a second wire carries a current of 9.75A parallel to the first wire. The two wires are 5cm apart. Determine the force on the second wire due to the first.

2. When an automobile moves at 15 m/s, its axles experience an emf of .00110 V. If the component of the earth's magnetic field perpendicular to the car's velocity and to its axles is 3.00x10^-5 T, find the length of each axle.

3. A 450-turn coil of diameter 2cm experiences an axial magnetic field of 1.6T. The field is reduced to zero, yielding an induced emf of 6V. How much time did it take for the field to drop to zero?
