In fact, the AlNiCo magnet was one of the strongest until recent advances in materials science passed it up. I don't know what the leader is now.
Under very high magnetic force, it has been demonstrated that most objects are magnetic. In fact, a recent demo on TV showed a spider suspended in a chamber, in mid air, by a huge magnetic field.
The electromagnetic forces allow electrons to create magnetic fields and magnetic fields create electricity. This has been known for hundreds of years, and was demonstrated by Benjamin Franklin among others. These fields can influence radiation, but they cannot influence light. Gravity can influence light, but there is no electrogravitic force or magnetogravitic force (as once was thought) that can combine all 3 forces and allow control over light, magnetiism and electricity.
