Unlocking the mystery, on how magnet attract stuff? Why it pull only certain things? Ever wondered why? And wanted to know, then come on. Let us start with a little experiment.
How magnets attract things?
Things: Atoms are tiny building blocks which make up everything around us. Atom is a collection of electron, proton, and neutron.
Magnets: Magnets or magnetic materials(things attracted to magnets) have a pair of electrons which are not stuck with each other.
Attract: Unpaired Electrons in both the materials (Magnet and Magnetic material) will look for available match thus attracted to each other (in simple English for kids).
How: And this is how magnets attract stuff 🙂
Types of materials:
All materials(things) are divided into two. Magnetic materials which are attracted by magnets like iron and nickel etc. Non-Magnetic materials which are not attracted by magnets like paper, glass, wood etc.
Domain theory: According to the domain theory, something like an iron bar contains lots of tiny pockets called domains. Each domain is a bit like a box with a magnet inside. The domain in the magnetic material aligns themselves with the domains in the magnet making thus attracting each other.
Basic principles of Magnet:
A magnet has two ends called North- Pole and South Pole
Like poles repel, unlike poles attract.
A magnet creates an invisible area of magnetism all around it called a magnetic field.
The north pole of a magnet points toward Earth’s north pole and vice-versa. Earth itself contains magnetic materials and behaves like a gigantic magnet.
If you cut a bar magnet in half, you now have two brand new, smaller magnets, each with its own north and south pole.
If you run a magnet a few times over an unmagnetized piece of a magnetic material (such as an iron nail), you can convert it into a magnet as well. This is called the magnetization.
Magnetic-field: a region around a magnetic material or a moving electric charge within which the force of magnetism acts.
Atom: basic units of matter and the defining structure of elements
Magnetism: it is a property of certain substances which pull closer or repel other objects
Repel: to force something or someone to move away
Poles: Either extremity of an axis through a sphere(earth)
