Abstract:
The objective of the Faraday’s Law of Induction lab was to verify Faraday’s law of induction by measuring the emf generated in a small coil and comparing it with the calculated value. Secondly the goal was to investigate the relationship between the emf and the frequency of the driving signal. The magnetic field was found to be uniform throughout. For the frequency of 40 Hz, the average current was found to be 0.634, the experimental magnetic field was found to be 29.21 Gauss while the average magnetic field calculated from the max and minimum values was 31.25 Gauss giving a percent error of 6.53%. V emf was calculated to be 0.03177V and the average voltage was found to be 0.0365V giving a percent error of 14.89%. For the frequency of 120 Hz, the average current was found to be 0.5675. The experimental magnetic field was found to be 26.14 Gauss while the average magnetic field was found to be 22.2 Gauss. Giving a percent error of 17.75%. The V emf calculated was 0.12257V and the average V was found to be .1025 giving a percent error of 16.45%.

Procedure: First the circuit was connected and the fuction generator output was set to the triangle signal with the aplitude about 75% of the max. The axial measurement was selected on te magnetic field probe. The pickup coil was inserted into the center of the solenoid in such a way that both axes were parallel. With the magnetic field sensor held at the center of the pick up coil the sensor was tarred to discount the ambient magnetic field . The magnetic field for the solenoid was then recorded for
