Neodymium Arc Magnets
Neodymium arc magnets are a type of rare earth magnet made from an alloy of neodymium, iron, and boron. They belong to the strongest class of permanent magnets available today, known for their exceptional magnetic strength and resistance to demagnetization. These magnets are typically shaped in segments of a circle, which makes them ideal for use in the construction of motors and generators where a curved magnetic field is required.
Their high magnetic strength allows for significant miniaturization in designs, making them particularly valuable in applications such as wind turbines, electric vehicles, and hard disk drives. Despite their strength, neodymium arc magnets are relatively brittle and vulnerable to corrosion, which often necessitates protective coatings such as nickel or zinc plating. They also exhibit high magnetic performance at room temperature but may lose some of their magnetism at elevated temperatures, requiring careful consideration in applications involving high heat.
