Abstract (4) The existence of Faradays Law was tested. First, the magnet was moved in and out of a solenoid to be recorded on the galvanometer. This was repeated with the inner and outer coil. Step up and step down transformers were then added to the circuit to measure their voltage. The ratio of the primary and secondary voltage transformers was then obtained using the LINEST function and the ratio for the transformer. The reciprocal for the step down and step up current was measured along with ratio for stepup with current. The results are as follows: voltage step up ratio = 8.419 ± 0.076, voltage for step down = 9.313 ± 0.235, current ratio for step down = 8.948 ± 0.202. Most values compared closely to the ratio on the transformer.
