There's a magnet in a secure room in central Tokyo. It's an electromagnet, the kind that generates a magnetic field when ...

A general magnetic propulsion system is composed of several electromagnets assembled with different orientations and positions. For remote actuation, the magnetic field produced plays an important ...

We present simple "best-case" calculations of power/lift and lift/weight ratios for iron-cored electromagnetic levitation systems using either the attraction between controlled electromagnets and ...
