Faraday’s Law Apparatus
This system allows for a complete investigation into Faraday’s Law, from teacher demonstrations to student experiments.
An acrylic tube supports an easily moved coil so that a small cylindrical magnet (supplied) can be dropped down the tube to generate a pulse of electricity (or electromotive force, EMF) as it passes through. A digital storage oscilloscope is used to monitor the pulse and measure its amplitude.
With coil tappings at 150 and 300 turns, the effect of varying the number of turns on the induced voltage can be examined. Further, by positioning the coil at various lengths along the tube, the speed of the magnet as it passes through the coil can be varied, and students can lead an investigation into how the rate of change of magnetic flux influences the EMF.
This demonstration is a must for introducing electromagnetism, and can easily be extended for experimentation as required.
Key features:
- Twin coil to allow for variation in the number of turns
- Easy attachment to a retort stand
- Tube assembly to guide magnet through the coil from various drop heights
- Supplied with cylindrical magnet of suitable shape and strength to generate a measurable EMF inside the coil
- Use to teach principles of Faraday’s Law, Lenz’s Law, electromagnetism and induction coils.
