How is antimatter stored?
Just like normal matter, anti-matter sometimes consists of
particles that have charges. And when a charged particle passes through
a magnetic field, the direction it is moving will be changed by the
field. It is possible to set up magnets so that these types of particle
basically gets stuck.
The simplest version of this is to set up magnets in a vacuum so
that if a charged particle comes into their field it will move in a
circle. The reason this has to be set up in a vacuum is so that there
is nothing, not even air molecules, for the anti-matter particle to run
into. This type of set up is usually called a magnetic bottle and would
be able to contain anti-matter.
