Neodymium bar magnets are powerful types of magnets made from an alloy of neodymium, iron, and boron. They belong to the rare-earth magnet family and are known for their exceptional magnetic strength and resistance to demagnetization compared to other types of magnets. Typically, these magnets are rectangular in shape, making them versatile for various applications, including in electronics, machinery, and even for personal uses such as DIY projects and crafts. Neodymium bar magnets are also commonly used in scientific experiments and for educational purposes to demonstrate magnetic fields and forces. Due to their strength, these magnets must be handled with care to avoid injuries and damage to electronic devices.
