Everyone is familiar with magnets and their attraction to iron and several other elements. Ferromagnetic attraction has been observed for thousands of years. It has an "opposite", the Meissner effect. However, mankind could not observe such an effect before the advent of refrigeration, which enables us to cool metals enough to become superconductors and hence exhibit Meissner repulsion. We have yet to observe the elusive twin to electric charge, magnetic monopoles. If there are any magnetic monopoles here on Earth, they are all probably bound in dipole pairs into magnetic neutrals. If we invent a new technology/technique, such as supercooling, we might be able to separate the magnetic neutrals into their constituent monopoles. So far, what are the techniques that people have suggested for obtaining magnetic monopoles?
