Introduction Objective: The objective of this experiment was to measure the magnetic field in a magnet by placing a loop inside the “gap” of another magnet. After measuring the magnetic field we will also measure the current and force from the magnetic field. In addition to measuring the current, force and magnetic field, we will use a 10Ω resistor to create a current through a dead loop, and use a scale to determine whether there is a force applied the magnetic is strong enough the change the overall weight of the magnet. Theory: The theory used in this experiment isn’t necessarily a law or a sanctioned theory but more of a rule. In this experiment we used the right hand rule to determine the direction of the current, force and magnetic field. However, we did not focus on this within the experiment. What we did focus on was the magnitude of the force, magnetic field and current. In order to find these values we used the equations: F=I ( l xB) where F represents the force exerted on a charge/wire/ field, and the l represents the length of the loop, and B represents the magnitude of the magnetic field. Also, if the
