Magneto-gravitons are powerfully attractive subatomic particles.
Magneto-Gravitons are a type of Exotic Particle - an Exotic Substance related to Etheric Science. A physrep of some kind of energy containment device can be used to represent up to 10 measures of this substance, but particularly large physreps can hold more.
A measure of Magneto-Gravitons can be applied to a Scanner to enhance its Sample function, granting +1 Green Card to Sampling when using the device. This will increase the chance of getting a positive result, and should allow more Samples or Exotic Substances to be obtained. Magneto-Gravitons applied to a Scanner may also be able to extract other Exotic Substances from trace quantities in the nearby environment - if a Ref is present, inform them of this effect after you complete your Examination, as they may determine that you are able to gain additional Exotic Substances of other types.
As with all Exotic Substances, a character with at least 1 rank in the relevant specialty (Etheric Science in this case) can spend 1 minute of appropriate roleplaying to apply 1 measure of Magneto-Gravitons to an item. After this roleplaying, they should unpeel the sticker that represents this substance, stick it to the lammie of the item being powered-up, and record the current date on it.
The boost provided by this substance wears off at time-out on the day recorded on the sticker.
