Hey, im doing some experiments of my own about magnetism, and was wondering if the some of the magnetic materials are MORE magnetic than other? (has a greater attraction to magnets/are better magnet shields/better at redirecting magnetic fields)
The strongest permanent magnet material we know of is Nd2Fe14B1 (or minor variations on this material). Prior to the discovery of NdFeB, the strongest was SmCo, prior to the discovery of that, the strongest was AlNiCo. The strongest magnetic fields are produced using electromagnets. As far as shielding or redirecting magnetic fields. A superconductor will prevent the penetration of a magnetic field. You can see an example of this if you google magnetic levitation, high temperature superconductor, and related terms.
