How do we use magnets in our everyday life?
Magnets are used to make a tight seal on the doors to refrigerators and freezers. They power speakers in stereos, earphones, and televisions. Magnets are used to store data in computers, and are important in scanning machines called MRIs (magnetic resonance imagers), which doctors use to look inside people’s bodies.

What do magnets attract to?
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.
What items are not magnetic?
Those materials which are not attracted by a magnet are called non- magnetic materials. All the substances other than iron, nickel, and Cobalt are non-magnetic substances for example plastic, rubber, water, etc are nonmagnetic materials. Non-magnetic substances cannot be magnetized.
Is Earth a magnet?
The crust of the Earth has some permanent magnetization, and the Earth’s core generates its own magnetic field, sustaining the main part of the field we measure at the surface. So we could say that the Earth is, therefore, a “magnet.”
What are the 7 magnets?
What are the different types of magnets?Neodymium iron boron (NdFeB)Samarium cobalt (SmCo)Alnico.Ceramic or ferrite magnets.
Who made magnets first?

Traditionally, the ancient Greeks were the discoverers of magnetite. There is a story about a shepherd named Magnes whose shoe nails stuck to a rock containing magnetite.
How do magnets come together?
It’s only when you hold unlike-poles together (a north pointing to a south) that magnets stick together (they are attracted). … Unlike-poles attract: When a north pole and south pole point together, the arrows point in the SAME direction so the field lines can join up and the magnets pull together (attract).
What are the 4 properties of magnets?
They are:Attractive Property – Magnet attracts ferromagnetic materials like iron, cobalt, and nickel.Repulsive Properties – Like magnetic poles repel each other and unlike magnetic poles attract each other.Directive Property – A freely suspended magnet always points in a north-south direction.
Which magnets are used in day to day life?
Magnets are used inside TVs, Sound speakers and radios. The small coil of wire and a magnet inside a speaker transforms the electronic signal to sound vibrations.
