### MAGNETIC SEPARATION – 42 Bio

Current magnetic separation technologies either employ a magnet attached to the side of a small tube, or a small tube with a magnetizable mesh inside. In the latter case, when a magnetic field is applied, the mesh becomes magnetized, trapping the particle/target components. However, there are significant limitations to both of these approaches.

### Magnetic separation - Wikipedia

Magnetic separation is the process of separating components of mixtures by using magnets to attract magnetic materials. The process that is used for magnetic separation detaches non-magnetic material with those that are magnetic. This technique is useful for not all, but few minerals such as Ferromagnetism/ferromagnetic (materials strongly affected by magnetic fields) and paramagnetic(materials that are less affected) but the effect is still noticeable). Not all metals are magnetic; gold, silv
