Faraday's Electromagnetic Induction Demonstrator

Faraday's Electromagnetic Induction Demonstrator
  • Faraday's Electromagnetic Induction Demonstrator
Ask For Price
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.

Ask For Price
A set of two transparent plates of size (155x76x6)mm has a matrix of small (14x7) circular chambers, each chamber containing a piece of iron rod and functioning effectively as a plotting compass. We can arrange the plates in various ways e.g. as single large two-dimensional surface and as the faces of cube, so in this way it may be used to show the configuration of a magnetic field in one or two dimensions with the attraction and repulsion properties of magnets. The transparent nature of plates also makes them suitable for use on an overhead projector. A set of bar magnet is also provided with the kit.
