mágneseket
Mágneseket are objects that produce a magnetic field. This field is invisible but has the ability to attract or repel other magnetic materials. Magnets are typically made from ferromagnetic materials like iron, nickel, and cobalt, or from alloys of these metals. The most common type of magnet is a permanent magnet, which retains its magnetism indefinitely. Electromagnets, on the other hand, are created by passing an electric current through a coil of wire, and their magnetism can be turned on or off.
The strength of a magnetic field is measured in units called teslas or gauss. Magnetic fields have
The discovery of magnetism dates back to ancient Greece, where lodestone, a naturally magnetized mineral, was
