Q-CDM48-G Block magnet 5 x 5 x 1 mm

NdFeB, N48, gold-plated

We produced this magnet especially for the CD-ROM model airplane engine do-it-your-selfers. It's a little bit stronger than the old Q-05-05-01-G (no longer offered) so the engines are a bit more efficient. Heat-resistant up to 80 degrees Celsius.
Naturally, there are lots of other uses for this small gold-plated magnet. It holds, for example, 2-3 pieces of A4 paper. It looks really nice when 2-4 magnets are used to hold up some paper. A very discreet thickness of only 1 mm.
This piece of a modified model airplane motor was designed by Claude Jäggi. He used 12 magnets for this.
An exemplary construction manual can be found at this website Wolfgang Korosec.

Magne Solheim from Norway sent us this photo. He has already successfully re-configured a dozen CD-ROM motors.
