Magnets

The strength of an electromagnet can be increased by increasing the number of turns in the coil or by increasing the current flowing through the coil.

An electromagnet is a type of magnet created by passing an electric current through a coil of wire wound around a soft iron core.

A permanent magnet retains its magnetism over time, while a temporary magnet only behaves like a magnet when placed in a strong magnetic field.

Every magnet has two poles: a north pole and a south pole. These poles exert the strongest magnetic force.

No, only ferromagnetic metals like iron, nickel, and cobalt are strongly attracted to magnets. Other metals like aluminum and copper are not attractive.

Neodymium magnets should be recycled properly due to their rare-earth elements. Contact local recycling centers or return them to the manufacturer for proper handling.

To maintain their strength and prevent unwanted attraction of metal objects, keep magnets in a dry, mild temperature environment and store them in pairs with opposing poles facing each other.

Magnets themselves do not generate electricity, but they can be used in generators to convert mechanical energy into electrical energy through electromagnetic induction.

High temperatures can weaken magnets by causing the random thermal motion of atoms, disrupting the magnetic domains.
