Answer:

1.Metals that attract to magnets Metals that attract to magnetsMetals that naturally attract to magnets are known as ferromagnetic metals; these magnets will firmly stick to these metals. For example, iron, cobalt, steel, nickel, manganese, gadolinium, and lodestone are all ferromagnetic metals.

2.Metals like brass, copper, zinc and aluminum are not attracted to magnets. Non-magnetic materials such as wood and glass are not attracted to magnets as they do not have magnetic materials in them.

3.Unlike a permanent magnet, the strength of an electromagnet can easily be changed by changing the amount of electric current that flows through it. ... As the current flowing around the core increases, the number of aligned atoms increases and the stronger the magnetic field becomes.
