Leedskalnin PMH demonstration, ferrite Permanent Motion Holder build, magnetic field experiment, and Coral Castle magnetism explained. Watch a working PMH made from junk parts, LED coil testing, and a historical breakdown of Ed Leedskalnin’s device.
In this video, I demonstrate a working Ed Leedskalnin Permanent Motion Holder (PMH), starting with a live magnetic lift test and LED flash coil verification. Using a salvaged ATX power supply ferrite core, I build and test a compact PMH powered by a single AAA battery.
You’ll see:
A real PMH lifting a steel keeper
LED flashing to verify coil health
Ferrite vs iron PMH construction
The history of Ed Leedskalnin and Coral Castle
Why this device stores magnetic alignment without oscillation
This is experimental magnetism, not perpetual motion — a fascinating look at forgotten electromagnetic demonstrations using modern junk-box parts.
👍 Like, subscribe, and share if you enjoy hands-on magnetic experiments and unconventional electrical history.
