GEOLOGY

Detailed explanation-1: -Iron nails, nickel, steel pen, and cobalt will be attracted to magnet and rest of the materials are non-magnetic in nature, so they will not be attracted to a magnet.

Detailed explanation-2: -Magnetic metals Iron is magnetic, so any metal with iron in it will be attracted to a magnet. Steel contains iron, so a steel paperclip will be attracted to a magnet too. Most other metals, for example aluminium, copper and gold, are NOT magnetic.

Detailed explanation-3: -Magnets attract the metals iron, cobalt, nickel, and steel, but they do not attract other metals. Magnets can attract or repel (push away) another magnet.

Detailed explanation-4: -Only ferromagnetic materials such as iron, cobalt, and nickel are attracted to magnetic fields strongly enough to be truly considered magnetic.

Detailed explanation-5: -The metals that are magnetic (attracted to magnets) are also the metals that can be made into magnets. The most common magnetic metal is iron which is the main substance in steel.
