Caution The transformer now operates with an open magnetic path. The losses in the transformer are high and the core will
get hot quickly. Do not leave the supply connected for more than a few seconds at a time.
One useful application of this method of levitation is for assembly line moving of devices. In particular, the method is
very attractive for the fast moving of silicon wafers in the production of semiconductors. The devices are levitated high
enough to eliminate friction and then, by properly sequencing the levitating coils, moved in any direction using the forces
generated between the coils and wafers.
