v Measure B Field Using Lorentz Force We can compare the measurement of the magnetic field strength using the concept of Lorentz Force. In the video below, the same magnetic gap assembly from the previous video is placed on a scale to measure the force caused by current flowing through a conductor immersed in the gap. 义 4294 1 The meter displays voltage (volts) on the left and current (amps) on the right. The central scale measures an effective massS m in grams (assuming a downward gravitational force of F = mg). The two side scales add together to similarly measure an effective mass of the wire and supports (the initial reading of the scale on the left is 161.40 g). Make a graph of Lorentz Force on the magnets, Fmag- VS current, I. in amps. Use this graph, along with other quantities you can measure from the video, to detemine the magnetic field strength (or flux density). B., in the gap.
