Electro magntic - Essay Example MS Excel once more helped drew the line of best fit and helped conclude that the relationship was actually also linear. The resulting formula has the ability to calculate the exact amount of force in any given length of coil. Even when the length of coil was varied, the resulting relationship was still consistently linear. Here is the formula: 3- The plotted points above show the relationship between the force and the magnetic field when the latter was altered. The graph shows a rather approximate linear relationship, and the general equation or formula is based on the line of best fit that is made through MS Excel. The formula is as follows: 4- Other relationships plotted above the graph of force tended to have nonlinear relationships with the varied angle. Theoretically, current-bearing conductors in magnetic fields with respect to altered angles tend to form sinusoids. The sinusoid is dependent on a number of factors such as current, magnetic field and the length of the coil conductor. Given that every other condition remains constant, the plotted graph assumes the form of a sin graph. Perhaps, the only discrepancy here is that the magnetic field is expressed in the number of magnets and not in SI units. Magnetic field is usually expressed in Teslas (T) and so there was a calculation to determine how much the consistent value of equivalent teslas is on the six magnets. The formula derived from this is as follows: Considering that our current, magnetic field and coil length were all constant from the results table, a specific angle was replaced with a force value in order to determine the constant value of Teslas appropriate for the magnetic field of six magnets, thus, 1. The doubling of the current will increase the value by a factor of 0.0058, which means that the current is actually directly proportional to the calculated force. Thus, it is expected that the force would increase. b. An electrical car that runs on an electrical
