- 2 Coax oil cm 9 cn 7 cm Al A large magnet requires a direct current of 5000 A. The leads are constructed as follows: A solid aluminum rod with a diameter of 5 cm is surrounded by a return lead in the shape of a hollow aluminum cylinder with an inner diameter of 7 cm and an outer diameter of 9 cm. Current flows into the magnet through the inner cylinder and out through the outer shell. (The space between the rods is filled with flowing oil to remove the heat. The presence of the aluminum and the oil do not affect the magnetic field.) The current density is constant over the cross section of each conductor. Use Ampere's Law to calculate and plot the magnitude of the magnetic field as a function of distance from the center of the wire. Start on the central axis and extend to a point 6 cm from the central axis: i.e., plot B(r) for 0arrow_forward58. An electric heater is tested by immersing it in 0.500 kg of water DATA and measuring the time At it takes to raise the water temperature by 10.0°C. The experiment is repeated for different currents I through the heater, and the results are tabulated below. Determine two quantities, based on heating time and current, which, when plotted, will give a straight line. Make your plot, determine a best- fit line, and use it to find the heater's resistance.
