The Ruhmkorff Coil, or Induction Coil

The Ruhmkorff Coil, or Induction Coil
Subject
Electricity
Description
This late 19th century instrument is often called a Ruhmkorff coil, after the Parisan apparatus manufacturer Heinrich Daniel Ruhmkorff (1803-1877). Although he did not invent the induction coil, his name is often associated with it (particularly in Europe) because he successfully put together all of the elements of the coil, including the use of the condenser connected across the primary to smooth the voltage output of the coil. Turning the crank handle rotates a magnet inside the coil in order to produce an electrical voltage.
