Capable of rapid acceleration, the Inductrack can operate in all weather conditions and varied terrain, requiring little maintenance.
Invented at Lawrence Livermore National Laboratory in California, Inductrack relies on permanent magnets arranged in a Halbach array on the underside of a maglev vehicle.

A 1997 study concluded that an Inductrack system would be cheaper than the German maglev, and "proved that the concept is workable," Post says.
A system recently developed at Lawrence Livermore National Laboratory, called Inductrack, uses a Halbach array of magnetic bars and shows promise, but is still in the experimental stage.
The Livermore team has developed a maglev design it calls Inductrack, which uses an arrangement of permanent magnets in a pattern called the Halbach array.
According to Richard Post, the Livermore physicist who invented Inductrack, it is this concentration that makes the use of permanent magnets practical.
Inductrack uses permanent magnets of neodymium, a rare earth, combined with iron and boron on the underside of the vehicle, which rides in a guideway lined with inductive coils.
