Are scissors magnetic?

Scissors are generally made of steel (iron). Iron itself is a magnetic material. The reason scissors are not initially magnetic is that the steel is made up of domains (small groups of atoms) which are magnetic (the atoms are “lined up”).

Are phones magnetic?

Most smartphones already have several magnets inside them.

You may already be aware that your smartphone has a number of magnets inside, for example, the speaker, the camera and the vibration module, none of which would work without magnets.

What are magnetic objects?

Magnets are objects, which can attract, or pull, on some metals, like iron and steel. If you rub a piece of steel with a strong magnet, the piece of steel will because a magnet too. It has become magnetized. Other metals, like copper or gold, are not attracted to magnets.
