I FUCKED UP MY PHYSIKS TEST!!!!!

Physiks - White Lightning EP - 2014

[fuforthought]

Look, I love British hip hop. It doesn’t matter what part of the country you’re from. If you’re dope, you’re dope. The first emcee on this track? I know he’s dope. But I’d be fucked if you’d ask me to tell you a word he’s saying. I just can’t do it. Glasgow emcees are unintelligible. With that said, this track is a bloody banger. Stick it in your ears.

Magnets

I was curious about how magnets, pieces of metals that mysteriously repelled and attract each other with invisible forces like magik, were able to just that. Hence, I searched it up and much of the information gave me a headache. HowStuffWorks, however, has nice graphical images that helped me understand a lot. Be sure to visit their website for any visual help!

So to summarise without a headache...(I try...)

Magnets as you know, are objects that creates their own magnetic field. A surrounding area around them that attracts (mainly) metals and attracts/repels other magnets.

Types of Magnetic materials:

Ferromagnetic and Ferrimagnetic materials are those that we can feel its forces of attraction because its strong enough.

Paramagnetic materials are super weak shits that we can't even feel its forces of attraction if it is multiplied a thousand times.

Diamagnetic materials are also weak shits. However, they repel magnets instead of attract them.

Everything is actually a magnet but what makes us call them a magnet are permanent magnets. Permanent magnets is an object made from a ferro or ferrimagnetic material and creates its own persistent magnetic field, whether natural or man-made.

OK, now for the main point.

How do they attract. Let's use our imagination as usual. Think of a hollow magnet that is bar shaped (NOT A BAR MAGNET). Yeah. Imagine there's a lot, A LOT of hyperactive crazy moving dots that goes in at one end of the magnet and out in the other and loops one round and goes back in the magnet again, all in the same direction. So, let's just say the end that dots go in is the "South Pole" of the magnet and the other end is the "North Pole". Now imagine another similar object with those dots...

If magnets were to be placed on the opposite direction, they would attract right?

Normally, the dots rushing out of the North Pole would turn back, however, since there's a South Pole nearer for them to enter, why not? Hence, the magnets are pulled.

I'll leave the repelling on your own. Think about it ;)

We talked about how magnets attract. But why not every object?

The reason is because magnets are actually made of tiny pieces of magnets... WHAT?!?!?!

Yeah... Those tiny magnets can be called as magnetic domains. These things actually contain North-South Poles too and they align to each other to form a magnet. If they were to point in opposite directions, meaning the dots would crash into each other, they would cancel out and thus, no magnetic force is created. Hence, the more "aligned" an object is, the more stronger its forces of attraction.

If you went this deep, you must want to know more. Here goes

Of course, we can go even deeper as to why the mini-magnets attract to form a large one. So why exactly do magnets attract?   What are those dots...?

They are actually electrons of the atoms of an object. If you went to school and studied your chemistry, you should know about the drawing of dot diagrams of your electrons. They are mostly in pairs, aren't they? In each pair, both move in a opposite direction and cancels each other out. However, some elements (mainly ferro/ferrimagnetic elements) have one or multiple unpaired electrons. Since they have no opposing pair, they all move in the same direction, creating a tiny force. When combined with other atoms, they create more force and with enough force, they can attract or repel similar objects, depending on their direction.

FYC (For Your Curiosities) :

Since there's mini-magnets in a magnet, just break a magnet and you'll have two!

Striking iron needles with magnets have always been a common and easy way to make a magnet. The reason for this is because those un-aligned mini-magnets will slowly rotate and become aligned.

Where there's a North Pole, there's must be a South Pole. Vice versa!

Something for making it through this waterfall of information…

If one side rejects you, do not worry as the other side will accept~

My understanding of fluidynamics was destroyed today...my teacher told me that the mass in kg is the volume in dm³ in water...and you don't have to mention the actual volume nor the density? So i thought that a cube that weights 7 tonns would be 7000dm³ in water but it isn't if the desity of the cube is that high and blarrg noone understands me TTATT
