A magnet is a material or object that produces a magnetic field, a region around the magnet where its force is felt. This field can attract certain materials, such as iron, nickel, and cobalt. Magnets are widely used due to their ability to create a force without physical contact. Key Features Attractive Force: Attracts ferromagnetic materials. Polarity: North and South poles Non-Contact Force: Exerts force without touching the object. Durability: Long-lasting magnetic effect Reusability: Can be used multiple times without losing strength Type: Permanent Alloy Materials: Neodymium, Ferrite, Alnico, Samarium Cobalt Coating: Nickel, Zinc, Epoxy (for corrosion resistance) Operating Temperature: Typically -40°C to 80°C Pull Force: From a few grams up to several hundred kilograms
