a)To make the solenoid, 1.0 mm diameter copper wire covered with a very thin layer of insulation is wound into a helical coil. The coil has a single layer of turns where each turn is touching the other. The solenoid has a length of 50 cm and a diameter of 16 cm. Calculate the current that is needed to produce a 140 μT magnetic field inside the solenoid. b) While testing the solenoid, a fly with a charge of 65 pC and speed of 1.3 m/s enters the solenoid. If the angle between the direction the fly’s motion and the magnetic field B = 140 μT is θ = 27°, determine the magnitude and direction of the force on the fly. c) The solenoid is used in a location where the Earth’s magnetic field is 50 μT and points horizontally. The bacteria are placed inside the solenoid and the current determined in a) is applied to produce a 140 μT magnetic field. What is the maximum and minimum value of the net magnetic field Bnet experienced by the bacteria? Explain
