Leave It To The Japanese: Dancing Paper Clip
Tweet
Electromagnetism leaking through the floor of a Kobe train causes paperclips to dance.
The video — shot on the Rokko Liner in Kobe, Japan — shows how paperclips stand on end when the train accelerates and brakes. The magnetism, which is produced by the electric current that drives the motors located under the floor, apparently poses no harm to the human body, though it could More..damage credit cards, mobile phones, or other electronic devices if left on the floor. The Kobe New Transit Company, which operates the Rokko Liner (as well as the Port Liner, which uses similar trains), says extra shielding is being installed just in case.
