About This Product
The interrupter repeatedly breaks the primary current, and the changing magnetic field in the core induces a very high voltage in the secondary, which illustrates Faraday’s law. The output is used to show spark discharge and to light spectral gas tubes for spectrum studies. Educational Instrument can dispatch the Induction Coil Apparatus to laboratories in Afghanistan, Angola, Malaysia, Togo, Bangladesh and Bosnia and Herzegovina.
