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
