Summary
DescriptionCallan Large Electromagnet (1836).jpg |
English: The first crude induction coil, also the first transformer, built by Nicholas Callan at Maynooth College, Ireland, in 1836. It consisted of a horseshoe-shaped piece of iron with two wire windings on it. When Callan applied a voltage pulse to the smaller primary winding, it induced a larger voltage pulse in the longer secondary winding. Part of the collection of the National Science Museum of Maynooth, Ireland. |
