Faraday's Electromagnetic Induction Demonstrator

Be the First to Review
For demonstrating the important experiments performed by Faraday and how they lead to some of the significant conclusions in electromagnetism. Designed to perform studies even beyond the basic experiments, it comprises three solenoids of 20, 40 and 80 turns, each of identical crosssection, mounted on a transparent base along with a milliammeter. Repeatedly inserting a magnet into the coil and removing it causes electric current to flow through the coil, which can be read directly from the milliammeter. Using this apparatus, students can study correlations between induced current to that of magnetic field strength, number of turns of coil, magnetic field polarity and speed. Requires 1.5V dry cell battery (not included), available separately.
