Permanent Magnets Used in Automotive Industry?

Vehicles need to be safer and more efficient than ever. Magnets are used in the automotive industry to achieve these goals and ensure a smoother car experience for us all.
Find out more about how exactly they’re used and why they’re important not only for vehicle safety but also efficiency.

In production, the magnets are often used for production, such as the magnetic driver used in the assembly of electronic products. During machining, a large number of fine iron filings will be produced. These iron filings will go back to the recycling container, which often leads to circuit blockage and cause inconvenience for cleaning. The machine tool can be equipped with a magnetic oil groove. During metal cutting, the cooling medium wrapped with iron chips flows into the oil groove from the oil drain groove of the workbench. When passing through the filter screen, the iron chips are blocked and accumulated on one side of the filter screen due to the action of annular magnet, and the cooling medium flows into the oil tank through the oil passage. When cleaning, it is very convenient to lift the oil groove and pour out the chips.

Magnets Used for Vehicle Safety

The automotive industry uses ceramic or ferrite magnets to make vehicles safer. One of the most impressive uses is in the Anti-lock Braking System (ABS). The magnets in this system slow the car down, while still allowing the driver to steer. The benefit is that drivers can try to avoid obstacles during accidents, whether it’s avoiding another car, a pedestrian, or a tree. ABS systems make accidents less severe or work to prevent them altogether.

Magnets are also used in the locking system, the windshield wipers, and the seat belt indicator. Thanks to magnets, you can lock your all of your vehicle's doors to avoid an attacker, drive safely in heavy rain, and avoid driving off without forgetting to put your seat-belt on.

Magnets Used for Convenience

Magnetic sensors help us keep track of how our vehicle is doing without always needing to visit a mechanic. In the past, you wouldn’t know if a part of your vehicle was out of place or if your door didn’t close properly.

These days, our vehicles use magnetic sensors that indicate if our tires are out of sync or if our door doesn’t close all of the way. Magnets are even used in your vehicle's tire pressure sensors. All of these sensors help you keep your car well-maintained.

Magnets Used for Efficiency

There are many different uses for permanent magnets in automotive applications, including efficiency. The automotive industry is focused on two kinds of efficiency: fuel-efficiency and efficiency on the production line. Magnets help with both.

Electric vehicles use magnets for all kinds of functions, but especially in the engine. In an electric engine, strong magnets surround the engine’s coil. Repulsion from these magnets is actually what forces the engine to spin.

More powerful magnets, like neodymium iron and boron magnets, are used in high-performance engines, such as those you might find on a race track.

Lastly, you’ll also find magnets playing a bigger role in the automotive industry’s production line. The faster a manufacture can perform vehicle assembly, without sacrificing car quality, the stronger their revenue. Magnets help speed up the process by holding heavy parts of the vehicle still, like the doors.
At Honsen Magnetics we understand that manufacturers need high quality magnets that will contribute quality and reliability to their product. Magnets are used in the automotive industry and many others. Contact us if you’re looking for a diverse magnet supplier.
