Document Summary
Abstract: this lab experiment revolved around trying to calculate an experimental value for 0. In order to do this a known gravitational force was used to balance the repulsive magnetic force between two wires with antiparallel currents. Then using an equation for magnetic force the 0 was found. In position 1 the slope was, 1. 111 x 105 1. 258 x 104 n/a2 while in position 2 the slope was, 8. 355 x 104 7874 n/a2 . These were averaged to be 1. 32927e-06 (n/a2) which yielded a 5. 78% error from the theoretical value of 0. Errors included: uneven/sloped bars, slight movements during the experiment, along with measurement error. This lab was overall successful as the experimental 0 was able to be calculated. In this lab experiment, a known gravitational force was used to balance the repulsive magnetic force between two wires with antiparallel currents. This was done in order to calculate an experimental value for 0, the permeability of free space.
