These are not ordinary globes but magnetic levitating globes. It is an impressive high-tech instrument with a magnetic field sensor permanently measures the height at which the globe sphere is suspended. The electronic sensors in the base control an electronic magnet in the upper part of the frame and therefore check the distance between globe sphere and magnetic head. An additional, permanent magnet in the base holds the sphere safely on the frame when the suspension mechanism is switched off.
