Frans Michel Penning's Watch

Origin
Frans Michel Penning (12 September 1894 – 6 December 1953) was a Dutch experimental physicist. He received his PhD from the University of Leiden in 1923, and studied low pressure gas discharges at the Philips Laboratory in Eindhoven, developing new electron tubes during World War II. The Penning trap stores charged particles by magnetic and electric fields. It was named after Penning by Hans Georg Dehmelt who built the first trap. Dehmelt got inspiration from the vacuum gauge built by Penning where a current through a discharge tube in a magnetic field is proportional to the pressure. Penning traps are currently used for magnetic measurements and are an active research topic.

Effects
Traps massive amounts of electromagnetic energy inside the watch.
