Magnets


When I was younger, sometimes I wonder how magnets work. I played with them a lot. Then I read a book about it and now I finally understand about the magnetic force and energy. I have decided to share this information with everyone.

First, as everyone should know, magnets can attract magnetic things such as iron and steel, but not things like aluminum and plastic. Second, two magnets can attract each other as long as their poles are not the same. If they are the same, they will repel. Third, magnets don’t use magic. They use a magnetic field, which I will explain in the next paragraph.


A magnetic field is a strong field around a magnet that attracts metallic objects or other magnets. A way to determine what your magnet’s magnetic field looks like is to sprinkle iron powder around the magnet and you should see that the pattern. This pattern is the same as the one in Earth’s magnetic field.


There are three types of objects in terms of magnetic force. The first type is a ferromagnetic object, which means that it is strongly attracted by magnets and can be made into a magnet. For example, iron. The second type is a paramagnetic object, which means that is weakly attracted by magnets. For example, chromium. The third type is a diamagnetic object, which means that it is not attracted by magnets. For example, plastic.

There are three ways to make a magnet.

The first way is called induction. If you place a piece of iron on a magnet, the iron will also become a magnet. This effect disappears if you remove the magnet attracting the iron.

The second way is stroking. If you rub a magnet along an iron bar in one direction continuously the iron bar will gain magnetic properties that will disappear over time. If you strike the iron more then the duration of magnetism will be longer.

The third way to make a magnet is to add electricity to a ferromagnetic object. The new magnet is called an electromagnet, and they are very powerful. Sadly, if you remove the electric current from the ferromagnetic object, the magnetic property will disappear. The strongest magnets are usually electromagnets.

Those are what I know about magnets. When I find any additional information about magnets, I will update this blog and gladly share the new info.

Thank you!

Vectors and Scalars

I want to talk about Vectors and Scalars . This is about physics. Now you might be asking, what is a vector? Vectors have a magnitude and direction. In case you don’t know, magnitude is the size of the movement, but it’s not distance. Since it’s a vector quantity, it’s called displacement .  For example, the displacement of a leaf being blown by the wind is 50 centimeters to the east. This is a vector quantity because it has a magnitude (50 cm) and a direction (east). And there’s more...  If someone asks you the version of speed in a vector quantity, it’s called velocity .  For example, the velocity of a ball being thrown is 5m/s to the east. In other words, five meters per second to the east.  You can find the displacement as long as you have the velocity and time. Multiply them and you will get the displacement. If the velocity is 5m/s and the time is 10 seconds, you need to multiply them ( 5 x 10 ) to get the displacement, which is 50 meters.  A...

Cheryl's Birthday Problem (from SASMO 2015) and Solution

Image
Hello! Nat here, and in this blog, I am going to discuss and give the solution to the famous Cheryl birthday problem. This was popular because it is a difficult logic puzzle and involving the ability of carefully tracking down hints in the conversation and working with only a small amount of data. Here’s the question: Albert and Bernard just became friends with Cheryl, and they want to know when her birthday is. Cheryl gives them a list of 10 possible dates. May 15           May 16           May 19 June 17          June 18 July 14           July 16 August 14       August 15       August 17 Cheryl then tells Albert and Bernard separately the month and the day of her birthday respectively. Albert: I don’t know when Cheryl’s birthday is, but I know that Bernard doesn’t know too. Bernard: At first I don’t know whe...

Black Holes

Image
Black Holes are holes in space that absorbs anything in their way, even stars. They are made by a star exploding as supernova and the star must be about 3 times the mass of the sun. This is called the Oppenheimer-Volkoff limit.  Its core will collapse into a neutron star, but its gravity is so strong that it starts sucking in material from outer space and later turns into a black hole.  Once they absorb enough matter to become powerful and massive, they can start creating galaxies. That is why black holes can be found in the heart of galaxies.  Sometimes, black holes will emit the brightest light waves in the universe – quasars.  Now you might be asking, why don’t we see like “blink, blink” from earth? The answer is that they are very far. The furthest quasar from us is about 14 billion light years away. However, we are lucky to be on a planet that isn’t near a black hole. If we were near a black hole, we would get our atmosphere stripped first then ...
