Which shape of magnets is the strongest?
At some point in life, you’ve maybe wondered why a magnet often is shaped and illustrated as a horseshoe. Well, it has something to do with the usage of it and also the strength of the magnet, sometimes indicated as the direct pull. But, its not because it's the strongest shape. But which shape is the strongest?
Which shape of magnets is the strongest? The strongest shape of magnet is actually of neodymium magnet in a steel pot. This means that if you want the strongest possible magnet, you simply buy a neodymium magnet and put in inside a steel pot. This gives the strongest possible shape of magnet.
This was the shortest possible way to answer the question: Which shape of magnet is the strongest? Of course, there is a lot more to it than that, which you can learn all about if you keep on reading!
Which shape of magnets is the strongest?
There are more important factors, which determine the strength of magnets. Size and materials for instance, but also the shape and surface of the pole is a matter of fact.
With no scientific background other than I loved physics during school, I used to wonder why a magnet always was shaped and illustrated as a horseshoe in pictures and movies. The magnets we used, was just shaped like a regular bar. I thought that the horseshoe magnet was the strongest, turned out i was wrong.
Now I know, that a horseshoe magnet is just a bar magnet shaped like a U to make it stronger, but there are still so many unresolved questions from the knowledge I learned in the past.
We learned about magnetic levitation and the high-speed trains in Japan, which was much faster than the ones we used, and also better for the environment. I thought, that it was just a matter of time before we used all these trains, and new discoveries I learned about in our everyday life.
A quick answer for the high-speed trains is, that is way too expensive, hard to implement and protected by patents and so on… Some things just take time.
But I never got deeper into the subject, magnetism. So, now I have a clear purpose with this post. It is to figure out, which kind of unique shapes of magnets there are in this world, the most common ones, and which one is the strongest?
-Is the world's strongest magnet really a neodymium magnet in a steel pot?
The World's strongest magnet
The world’s strongest magnet is allegedly placed in the National High Magnetic Field Laboratory at Florida State University. I will be fast to disappoint you by saying:” No, it’s not a neodymium magnet in a steel pot”.
According to researchers, it has the potential to revolutionize scientific research. The world’s strongest magnet is 500.000 times stronger than our planet's magnetic field, but was does that even mean? Not that much, but...
It means it has the potential to deepen our understanding of, how our planet works. Super powerful magnets help researchers in the field of medical research, chemical reactions and even quantum computing.
You measure magnets powers by using tesla-units. It is a derived unit of the magnetic induction named after the Serbian-American inventor Nikola Tesla. Besides giving the name to the famous automotive and energy company, Tesla is also a unit and designation for the magnetic field.
The pulling power of the worlds strongest resistive magnet is measured to be 41.4 teslas. Another unit of magnetism is Gauss, named after the German scientist Carl Friedrich Gauss.
To clarify the power of the world's strongest magnet, a strong refrigerator magnet is 100 gauss. In one tesla-unit there is 10.000 gauss. This means, that the power is stronger than the combined power of more than 4000 strong refrigerator magnets.
Depending on where you have your sources from, there are different facts on this subject on the internet. Some claim, that there is built a magnet there has a record-setting magnetic field of 100 tesla-units.
It can be hard the relate to these units and numbers. No matter what, the continuous breakthroughs with magnetism will probably soon have an effect which is easier to understand for the common people.
Sad to say, that the picture I found of the world's strongest and biggest magnet was more shaped like a big cylinder, with a weight of 34 tons. This means, that the world's strongest magnet is not as i described before. That does not necessarily mean, that the shape is not to consider the strongest shape of a magnet.
The size and the material of the magnet is a very big factor when you have to design the world's strongest magnet. We have taken a closer look of, what various uses and shapes the most common magnets have, that you can find in your daily life.
The different shapes of magnets
There are many unique ways of shaping and using magnets. In earlier posts, we have described some of the different types of magnets, where neodymium magnets are considered as the most powerful permanent magnets in the world.
So, without thinking too much of the material and size, we have found four different shapes of magnets, that are the most commonly used.
It is possible to make magnets in any 3D shape you want. As earlier mentioned the most iconic and illustrated magnet is the horseshoe magnets, which also have the same form as the letter U.
The shape makes the magnet more powerful by pointing the poles in the same direction and creating a strong magnetic field. It is made by bending a regular bar magnet into a horseshoe shape.
The strongest part of a magnet is concentrated at the poles. That is why a horseshoe shape is considered the strongest and can be very useful to create if you want to lift heavy objects or want to make a bar magnet stronger.
It is shaped like a bar with a pole in each site. Often it’s made in blue and red colors with the letter N and S to show which pole the end is attracted to. The north pole of one magnet attracts the south pole of another magnet.
A bar magnet is considered as the weakest magnets because the poles have the smallest area. It is often used in school to show the students a regular permanent magnet, and it is commonly known from the refrigerator, to hang up objects on the fridge.
Cylinder & Disc Magnets
A cylinder magnet is shaped like a cylinder. Mostly it is defined by the diameter. If it is equal to or smaller than the height, it is considered as a disc magnet.
The shape of the diameter can cause a bigger pole, which means, that you can make your magnets stronger, by giving them a bigger pole.
So, depending on how big you make your cylinder or disc magnet, you can make them very powerful by creating a bigger surface. Just as they have done to the world's biggest magnet.
It’s not only the horseshoe magnet, which is designed to lift heavy objects. You also use disc magnets to lift cars and other huge objects.
In daily use, you can also use disc magnets as earrings or through clothes, for example by attaching your race number on, during a competition. Take a look at our sports magnets.

They are most known for toys and are also called Neo cubes and Zen-magnets.
A sphere is a perfectly round geometrically object.
It can be very relaxing and de-stressing to use sphere magnets, and it’s another fun way in which you can create, shape and use magnets.

50 shapes of magnets
As I mentioned in the beginning, I have always been curious about, why we don’t use the science behind levitation magnetism more in our everyday lives. The reason is, that it is expensive and hard to implement and sometimes protected by patents.
But that can be a hard world to follow. Try to be creative with your own magnet-experiences, and get inspired by some our selection.
It is easy to come up with 50 different shapes of magnets. It has many facts and functions in both science, industry and daily life, where we at Magnetpartner enjoys coming up with new creative ways to use magnets.
In some of the following blog-posts, we will try to be better to inspire to DIY-projects where you can use magnets in your everyday life.
