How are chargeless particles such as neutrons isolated from other types of matter?

One way to isolate neutral particles is to take advantage of the fact that they don't react to a magnetic field.  By applying a magnetic field to, say, a beam of positively charged, negatively charged, and neutral particles, you can strip away the charged particles, leaving the neutrals.
