Uses for our rare earth block magnets

Magnets like these neodymium blocks would have been installed in film projectors to regulate the movement of metallic parts. The speed at which individual frames containing the filmic images pass over the projector’s light beam is vital. Moving images moving too fast or too slow disorients the viewer, countering the suspension of belief or emotional investment the filmmakers are asking audiences to make.

Rare earth block magnets express instinctive or intuitive magnetic power. Nearby metallic components can move, but only at pull or quit the magnetic grip force determined by the magnet’s strength. That is the intuitive or instinctive nature of magnetic power.

We originally had this magnet manufactured for the Film & Cinema industry. It is used in part of the componentry that makes up a film projector used in the older style cinemas of the past. These particular movie projectors are still used to this day and we believe there are several hundred in operation worldwide. We presently have about seven hundred pieces in stock and will not be replacing this size once all stock has been sold.
