In this article, we'll learn about the science of magnets. We'll see how a compass works and find out why it points north. We'll also look at electromagnets and permanent magnets -- what makes them work? And finally, we will take a look at some fun things you can do with magnets!
A magnet is an object that attracts certain metals like iron or steel. Magnets have two poles: North (N) and South (S).
The Earth itself acts as one giant magnet; its magnetic field extends into space in all directions from the planet's centre. A compass needle aligns itself along this field so that it points to the geographic North Pole -- which is actually not located exactly on top of true north but rather slightly off-centre toward Canada due to Earth's rotation around its axis!
The fact that compasses point north has been known for thousands of years, but only recently did scientists discover why they do so: It turns out there are tiny particles called electrons inside every atom in our bodies as well as everything else around us including rocks themselves!
These electrons spin around their nuclei just like planets orbit stars or moons orbit planets -- except these electron orbits are much smaller than those found in celestial objects such as stars or moons because atoms are very small compared to celestial bodies such as suns or even asteroids for example...Electrons spin either clockwise (called "spin up")or counterclockwise ("spin down").
In most materials made up primarily by nonmetals like oxygen, nitrogen and carbon compounds among others), most electrons tend to be "spin down." But when you get pure metal elements such as iron(Fe), cobalt(Co)and nickel(Ni),most of the electrons are "spup".
This means if you put two pieces of metal together with opposite spins facing each other then they will repel each other while if both pieces have same-direction spins then they attract each other strongly enough to hold together despite gravity pulling them apart since unlike charges repel while likes attract.
This explains why when you rub your feet against carpeting your socks stick onto your skin instead falling off immediately after taking them off.. When rubbing occurs between different types of material surfaces with rubber soles vs leather uppers etc., friction causes heat buildup which melts surface molecules causing adhesion via molecular bonding forces.
