Do magnets work on the moon?
The magnetic field of the Moon is very weak in comparison to that of the Earth; the major difference is the Moon does not have a dipolar magnetic field currently (as would be generated by a geodynamo in its core), so that the magnetization present is varied (see picture) and its origin is almost entirely crustal in …
Can vending machines detect fake money?
Some vending machines use ultraviolet scanners to measure the glow from a bill to verify it is real. Real currency bills are also printed using magnetic ink. Many vending machines also use a magnetic reader to detect the magnetic signature of a bill to ensure it’s real and determine its denomination.
