Is Zinc Magnetic - University Of Maryland

Pouring Zinc from the Penny. What is interesting is that even though zinc isn't magnetic is can interact with magnetic fields. If you move a strong magnetic you can actually cause small currents of electricity to flow in the zinc. These small currents have a magnetic field opposite the moving magnetic. As a result they push away and the zinc ...

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 who are magnetic. This technique is useful for not all, but few minerals such as ferromagnetic (materials strongly affected by magnetic fields) and paramagnetic (materials that are less ...
