I need it for a science essay. please help
Up to a certain level of field, superconductors
Sideshow bob is right. Supercondutors will not allow a magnetic field to penetrate. If the magnetic field is strong enough, it will force the superconductor to stop superconducting and then the field will penetrate. Research Eddy currents.
magnetic field strains r closed loops so as that they are going to pass via any substance if u enclose one pole with any substance. inspite of the undeniable fact that, diamagnetic aspects tend to dam the sector from passing via them.u would b involved 2 know that superconductors tend 2 repel magnets regardless of the pole dealing with them
