Who makes magnets for cars?

Many companies make magnets for use in cars, but there isn't one single manufacturer that supplies *all* the magnets. The magnets are used in various components, and different suppliers specialize in different types and sizes.

The companies involved can be broadly categorized:

* Magnet Manufacturers: These companies produce the raw magnetic materials (like neodymium, samarium cobalt, ferrite) or finished magnets in various shapes and sizes. Examples include (but are not limited to) Hitachi Metals, Shin-Etsu Chemical, and various smaller specialized manufacturers. Many are not well-known to the general public.

* Automotive Component Suppliers: These are larger companies that design and manufacture various parts *containing* magnets for cars. They source magnets from the manufacturers above. Examples include Bosch, Denso, Valeo, and Continental. These companies integrate the magnets into things like motors, sensors, actuators, and speakers.

* OEMs (Original Equipment Manufacturers): The car manufacturers themselves (like Ford, GM, Toyota, etc.) don't typically make the magnets, but they specify the requirements and source the components from the automotive component suppliers.

So, there's no single answer to "who makes magnets for cars?" It's a complex supply chain involving many specialized companies.
