Magnetism Notes
Heat will reduce the strength of magnetic field. This is important to know when using the
magnetic brake for long periods of time. If is recommended to keep the amount of time that the
magnetic coils are energized as short as possible.
When the coils of the magnet are energized, the electrical current flowing through the coils
creates heat. Keeping the brake in open air and if the ambient temperature is high, it may help
to use an external fan to provide some air movement.
Magnetic materials such as the steel used for the clamping bars will become weakly magnetized
by being in contact with strong magnets. Over time with use, these bars will gain their own
magnetic field. Over time when not in use, this magnetic field will dissipate and weaken.
If the magnetic brake is used daily, this relatively weak magnetic field will remain constant.
Also striking metal bars with a hammer can create a temporary weak magnet. This is important
to know with regard to handling the clamping bars.
First, the clamping bars should be handled carefully to prevent damage and bending.
Additionally, if the bars are dropped or moved around roughly, this can cause the natural
magnetic field created from usage to strengthen slightly as well as last longer.
This can cause some issues with the clamping bars releasing after a bend.
Use sources such as library or the internet to find methods for de-magnetizing steel if the
clamping bars become too magnetized to use effectively.
NOTICE: This brake has a 30% duty cycle. If the bending bed, (magnet) is too hot to touch
then the brake should be completely shut down and allowed to cool to prevent damage to
the magnet coils.
