Physics II Laboratory Faculty of Science, Ontario Tech University Magnets are attached to and balanced on a balance. One of the current loops is held in place by the magnets. Prior to any current going through the conducting channel, the balance is used to measure the mass of the magnets. The current is then transferred through the conducting route, producing a force that causes a change in mass and thus a change in the balance reading. The magnetic force between the conductor and the magnetic field can be calculated by dividing the difference in balance mass readings with and without the current by g which is the acceleration due to gravity. To vary the current delivered to the conductor, a power source is used. In this experimental setup, the current direction is always perpendicular to the magnetic field vector, therefore angle = 90°, which ignores the sin component of the expression. To find the mean value of the magnetic field in the first experiment, determine the slope of a Force Vs Current graph and divide it by the length of the loop. In the second experiment, to calculate the mean magnetic field, take the slope of a Force vs Conductor Length graph and divide it by the current. The B value and magnetic field value were similar in both studies, which makes logical given that we used the same magnet in both. This value was expressed in Tesla or NAm units. The magnetic force is shown to be directly proportional to the magnetic field, conductor length, and current in all three trials. This yields the equation F =ILB, where F denotes magnetic force, I denotes current, L denotes conductor length, and B denotes magnetic field. As previously stated in this experiment, the magnetic field's direction is always perpendicular to current. However, because this is not always the case, a modified version of the expression is F= ILB sin(theta), where is the angle between the magnetic field and the wire (current).
