Attractive Magnet

ATTRACTIVE MAGNET

Experiment Video:

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.

  Tips: 
Howdy, young scientist!  Have you enjoyed today’s video?
Feeling excited! Well, of course, you will be. After all, who hates to play with magnets. Without further due, start with your experiment.
As you know, scientist always keeps a record of his/her works. To help you with this, feel free to use the following freebie.

Reasoning:

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 🙂

Scientific Learning:

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:

1. A magnet has two ends called North- Pole and South Pole

2. Like poles repel, unlike poles attract.

3. A magnet creates an invisible area of magnetism all around it called a magnetic field.

4. 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.

5. If you cut a bar magnet in half, you now have two brand new, smaller magnets, each with its own north and south pole. 

6. 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.

Vocabulary:

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)
