What Are the Best Magnets?
It can be a tricky thing to determine which type, shape or size of magnets that are the best. Especially if you are inexperienced with projects that involve magnets, choosing which magnet can be both difficult and confusing.
But fear not, in this post you will learn more about which things you need to consider when choosing the magnets for your project.
What are the best magnets? The best magnets depend fully on which project and application the magnet is going to be used in. It also depends much on how much money you wish to spend and how much strength you need. If you value a low price higher than a ferrite magnet might be the best. If it's the quality, a neodymium magnet is to prefer.
Now we will walk you through 2 different types of magnets and explain the pros and cons of them. After reading this, i'm sure you will feel much more comfortable with choosing the magnets for your next project. Good luck!
When are neodymium magnets best?
If you need a magnet with impressive strength and small physical size, and the economy is less important, a neodymium magnet is probably the best magnet for your project.
Neodymium magnets, also called power magnets, is extremely powerful magnets. Not only are they the strongest permanent magnets currently known, but they are also much lighter and cheaper than other magnets compared to other types of magnets.
Our powerful neodymium magnets can hold items that weigh many times their own weight.
The exciting thing about the strong neodymium magnets is the many possible applications to use them for, because of their tiny size and impressive strength. Neodymium magnets are used for countless things.
The magnets are used in everything from Warhammer figures and glass-boards to magnetic mixers and metal separation in feeders.

A short introduction to neodymium magnets
As you might have guessed from the name, neodymium magnets are made with the rare earth metal neodymium. The magnets chemical name is NdFeB magnets.
Neodymium magnets will not decline in strength for the first 100 years unless you expose it to multiple hard strokes and/or powerful heat. The main part of our neodymium magnets can withstand temperatures up to 80 Celsius degrees, but if it is exposed to even higher temperatures, it possibly will be damaged.
In terms of low temperatures, there is no bottom limit for cold temperatures a neodymium magnet can withstand.
Neodymium magnets are perfect for DIY projects, and one of my personal favorites is a knife-holder. It’s actually pretty easy to make one yourself.
First of all, you need a piece of wood, a tile or something else you think could make a nice holder for your knives. Unfortunately, we cannot help you with the first part, but we can supply you with the magnets.
- Step 1:
Pick the material you think will make a nice holder.
- Step 2:
Mill a groove or round pockets on the back of the material. The holes are made to put the magnets in.
- Step 3:
At a good distance, attach the magnets to the back of the material. If you have chosen a long groove, they must be glued with two-component adhesive. If not, they will be attracted to each other at a very high speed and break.
- Step 4:
Attach one magnet at the time and let it dry for a few hours before attaching the next magnet. The distance between the magnets must be the same distance you want the knives to have between them.
When all the magnets are attached, you simply have to put it up on your wall, and then you have it, a brand new knife holder!
You need enough distance from the wall to the knives, if you don't have enough distance, the knife will hit the wall every time you detach it. Therefore, it is a good idea to choose a piece of material that is a minimum of 2 centimeters wide.
When you need to choose the magnets for this kind of projects, you need to consider the weight of the knives you intend to hang on the holder.
For smaller knives, you can settle with 20 x 5 mm. neodymium magnets. (Or 20x20x5mm, if you want them in squares)
For big and heavy knives you need 20 x 10 mm, 25 x 7 mm or 35 x 5 mm neodymium magnets. In this case, you can choose a magnet that fits you, holder. They can all carry around 11 kilos, which is necessary, since there is a distance between the magnet and the knife, and it could be a disaster if the knives were to fall down because of too little magnetism.
When are ferrite magnets best?
If you are brand new within the magnet project, or you simply just need a low-cost magnet, where strength isn’t that important, a ferrite magnet might be the best choice for you.
Ferrite magnet is also very useful for applications that take places outdoors because it is very resistant to the elements of nature.
Ferrite magnets are like neodymium magnets a very common type of magnet. Its commonly referred to as “hobby magnets” or “fridge magnets”. The strength of a ferrite magnet is far less powerful compared to a neodymium magnet, which also is reflected in the price pr. unit.
Our ferrite magnets have no coating, but they can as mentioned before be used for outdoors purposes because they will remain stainless.
Besides being stainless, they are also extremely resistant to massive heat. They can withstand temperatures up to 250 Celsius degrees.
A short introduction to ferrite magnets
Ferrite magnets are both used for hobby and industry. The pros of this type of magnet areas mentioned its resistance to fluids and outdoor elements. And they are much cheaper than neodymium magnets.
But, compared to neodymium magnets, they are also quite heavy. You will often end up using a much bigger and heavier magnet compared to using a neodymium magnet.
Ferrite magnets can be a bit fragile as there is no coating on them. There can quite easily be knocked off small fractures of them during transport, storage, and use. But, the good thing about them is also that even if it breaks, it won't make much of a difference.
The magnetic field and strength of it won't be affected much if its just small pieces that have been knocked off. It only really gets broken if its cut in half.
So, if you want a cheap and resistant magnet, where power isn’t that important, a ferrite magnet would probably be a great option.
What to consider when choosing a magnet
At this point, you should feel slightly better informed when it comes to the two most common and widely used types of magnets. They both have pros and cons and choosing which magnet is the best really depends on what you need to use it for, and how much you are willing to spend.
If all you need a magnet is for I hanging some papers and drawings on your fridge, a ferrite magnet should be more than enough.
But, you should not attempt to do a project where a strong magnet is recommended with a ferrite magnet. The result will either be bad or a complete disaster. For example, the DIY knife-holder should not be made with ferrite magnets, but neodymium magnets instead.
