Magnets

Magnets are objects that produce a magnetic field, which can attract or repel certain materials, primarily metals like iron, nickel, and cobalt. They have two poles: north and south. Opposite poles attract each other, while like poles repel. This magnetic force is used in various applications, from holding notes on a fridge to powering electric motors and generators. Magnets can be permanent (staying magnetic over time) or temporary (losing their magnetism when removed from a magnetic field). Understanding magnets is essential in technology, medicine, and everyday life, as they play a crucial role in many devices we use.
