Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which object would a magnet attract?
A
a glass bottle
B
a piece of paper
C
a steel paper clip
D
a rubber eraser
Explanation: 

Detailed explanation-1: -Magnets have the ability to attract certain metals like iron and steel. Metal paper clips are made from steel and should be attracted by a magnet.

Detailed explanation-2: -Magnets attract paper clips because magnets have a magnetic field, which creates a force, that pulls on other ferromagnetic materials. A paper clip is usually made of steel wire. Steel is an alloy of iron and carbon. Iron is a ferromagnetic material that is attracted by magnets.

Detailed explanation-3: -Metals That Attract To Magnets Metals that naturally attract 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.

Detailed explanation-4: -If the pole of the magnet is changed, the paperclip also swaps sign (from north to south, or vice versa), so the force remains attractive. This is why both ends of a magnet can attract a paperclip . . .

Detailed explanation-5: -Metals are the only substances that are magnetic. The most common magnetic metal is iron. You don’t see too many products made of pure iron but you do see a lot of products made of steel. Since steel has a lot of iron in it, steel is attracted to a magnet.
