Explanation:
Detailed explanation-1: -A magnet wrapped in cloth will attract paper clips. Q. What material is attracted to a magnet? Q.
Detailed explanation-2: -In most substances, equal numbers of electrons spin in opposite directions, which cancels out their magnetism. That is why materials such as cloth or paper are said to be weakly magnetic. In substances such as iron, cobalt, and nickel, most of the electrons spin in the same direction.
Detailed explanation-3: -Magnets are attracted to items made of iron, cobalt, nickel, and steel. Paperclips are traditionally made of galvanized steel wire, which means paperclips are magnetic.
