Question: Calculate the length of the wire. Compare this length with the measured one by using ruler. By this point in the course, you have practiced experimental design enough to develop your own procedure for discovering mathematical relationships. Our goal is to discover how each factor affects the amount of force on the conductor. The factors we are interested in are: the magnitude of the current in the conductor the length of the conductor immersed in the field the strength of the magnetic field The videos below allow you to vary the strength of the magnetic field, the current, and the length of the conductor immersed in the field. While you can use tools in the video to measure current (ammeter) and conductor length (ruler), you can't directly measure the magnetic field strength. The manufacturer publishes the field strength at the center of the surface of these magnets as follows: Magnet A: 0.2012 T Magnet B: 0.3424 T Magnet C: 0.4305 T Magnet D: 0.4871 T Let's start by exploring the relationship between force exerted on the conductor and the magnitude of the current flowing through the conductor.
