Permanent magnets are typically made from materials like:
– Neodymium (NdFeB): The strongest type of permanent magnet, used in motors, sensors, and high-tech devices.
– Samarium-Cobalt (SmCo): High-temperature and corrosion-resistant, used in aerospace and military applications.
– Alnico: Composed of aluminum, nickel, and cobalt, used in applications that need moderate magnetic strength.
– Ceramic (ferrite): Made from iron oxide and barium or strontium carbonate, used in speakers, magnets, and other everyday items.
