Why do EV motors need permanent magnets?

The stator’s rotating magnetic field interacts with rotor magnets to produce torque, and permanent-magnet motors generally offer strong efficiency and power density.

Who supplies GM’s automotive-grade magnets?

MP Materials, which makes them at its Independence facility in Fort Worth, Texas.

What does “buy where we build” mean?

It is GM’s approach of sourcing close to where it builds, shown here by linking California, Texas and Michigan operations.

What is a foundational customer?

A customer that provides early demand certainty and technical alignment so a supplier can industrialize and scale a new capability.
