One of my objects / soft batons sometimes stays stuck to the magnet.

How long do the batons hang on the machine ? Is the machine sitting idle for long times while turned on (not recommended) ?

As with all electromagnets, prolonged contact with metal can cause a bit of residual magnetism in metal objects. This means that if a baton stays in contact with the magnet for an extended period, the metal on the baton can temporarily become slightly magnetic as well. In some cases, this residual magnetism may be just strong enough to hold the baton for a short time even after the magnet is turned off.

There are two simple ways to prevent residual magnetism:

1. Keep the contact time short – which usually happens naturally during active gameplay. Avoid leaving the machine idle with the batons held in place for long periods.
2. Add some weight to the batons – this helps them fall away more easily when the magnet turns off , but naturally we try to keep the weight of the batons to a minimum.

If you need batons to stay on the game prolonged, the easy fix is to remove the cap at the bottom of the baton, insert a small metal washer or some weight, and then press the cap back on. This adds just enough mass to overcome any lingering magnetic attraction.
Also, any residual magnetism naturally fades away over time once the batons are not in contact with the magnets.

tip : Do not let your reaction ring sit idle for long periods of time with power on as this continuously sends power to the magnets.
