LARMOR neutron microscope

A Larmor Neutron Microscope is a kind of microscope that uses a beam of neutrons to look at very small things. It works by shooting out a beam of neutrons in order to see the atomic particles inside whatever you’re looking at. The neutrons hit the atoms and make them move in tiny circles called "Larmor precessions". This movement creates an electric field around the atoms, which the microscope can detect and use to build a picture of what’s inside.
