Oct 22, 2018· An Iron Needle sticks to the Magnet when brought near it. But why only when it''s near the Magnet? Why not from a distance very far away? Well it depends on the Strength of the Magnetic Field.
It is the number of magnetic field lines passing through a surface ... (electric field, bananas, whatever you want) passing through a surface. The total flux depends on strength of the field, the size of the surface it passes through, ... Iron ore and iron slag can also both be magnetic. See Full Answer. 15.
A second, higher magnetic field strength may be applied at 34 to the remaining material to separate out the iron oxide rich product which is more magnetically susceptible than the silicate rich product. The magnetic field strength can be adjusted by selecting the appropriate permanent magnet or by the use of an electromagnet.
Feb 17, 2017· Thanks to the magnetic properties of ironoxide particles found in clay – which record the intensity of Earth''s magnetic field when heated – scientists have discovered a hidden history of Earth''s fluctuating magnetic field in the years from 750 to 150 BC.
