1) Two wires each of length I with current I are placed parallel to each other separated by a distance d. What physical quantities can you determine using this information? How will the values of these quantities change if one of the currents is reversed? If one of the currents is doubled? Include a diagram to explain your reasoning.

2) An electric motor has a square armature with 500 turns. Each side of the coil is 12 cm long and carries a current of 4.0 A. The magnetic field inside the motor is 0.60-T. Choose two orientations of the coil for which you can calculate force-related and torque-related quantities. Draw pictures to show the relative orientations of the coil and the magnetic field vectors.

3) An electron enters a solenoid at a small angle relative to the magnetic field inside. Describe the electron’s motion. Include a diagram to explain your reasoning
