Magnetic water de-hardener changes physical parameters of salts passing through the magnetic field and – if pronounced in a simplified form – it “softens” the water, thus limiting lime-scale deposition significantly.
This magnetic rod is used to test whether your material contains metallic-magnetic impurities. The rod is fitted with very strong NdFeB magnets. You can remove the impurities by sliding the magnetic core out of the stainless steel case and metallic particles will fall off.
