How anti-theft tags work - magnetostriction

Anti-theft tags contain a tiny mechanical oscillator that is activated by a magnetic field.  The detectors at a shop's doorway can detect the oscillation magnetically. The tag can be activated and deactivated by magnetizing or demagnetizing it, respectively.

Your toothbrush is worn-out!

See how your trusty toothbrush becomes worn out.

Special thanks to Harri Lähteenmäki  and Johannes S. Zwilling for sending me the smooth zoom footage of the tungsten filament, and showing me how to use After Effects to get a much better effect.  I really appreciate it!  http://www.videocopilot.net/tutorials/earth_zoom/

Smooth zoom video from SEM

I manually interpolated the sequence from about 15 single frames from the SEM.  Smooth zooming is not possible on the instrument natively.
