Which metals are attracted to electromagnets? check all that apply.

-aluminum
-cobalt
-iron
-copper
-nickel

Cobalt , Nickel and Iron

Explanation:Magnetism is the phenomenon which is caused by the motion of the electrons in the substance and its spin alignment with the its neighboring electron spin.

Ferromagnetic materials like iron , cobalt and nickel form permanent magnets exhibiting strong magnetic effect and they maintain their continuity of electron alignment even in the absence of magnetic field

Paramagnetic materials like aluminum are weakly attracted to the magnetic magnetic field and they do not retain their magnetism in the absence of the field.

Diamagnetism is exhibited by copper and other materials are repelled by the magnetic field.
