Physics, Astronomy & Cosmology / How much iron is needed to stop opposing forces of magnetic poles?
« on: 16/06/2020 03:31:54 »
If we put two opposing magnetic poles facing each other, those magnets will be pushed apart by a magnetic force. But if an iron plate is inserted between them, the pushing magnetic force can be reduced or even reversed into a pulling force.
Is there a formula determining how thick the iron plate is required to neutralize the pushing magnetic force between the same magnetic poles?
