Wimshurst Induction Machine

Wimshurst Induction Machine

The small electric charge on the tinfoil sectors built up rapidly as the two varnished glass discs were rotated in opposite directions. James Wimshurst invented his high-voltage generator in 1881 and it immediately became a popular laboratory instrument. Unlike earlier induction machines it was 'self-exciting', that is it did not need a starting charge. It also worked reasonably well in damp weather.
