How to tell if a flat square magnet is real or fake?
Oct 29, 2025| Hey there! As a supplier of Flat Square Magnets, I've seen my fair share of real and fake magnets out there in the market. It can be a real headache trying to tell the difference, especially if you're new to the world of magnets. But don't worry, I'm here to help you out. In this blog post, I'll share some tips on how to tell if a flat square magnet is real or fake.
1. Check the Material
The first thing you need to do is to check the material of the magnet. Real flat square magnets are usually made from neodymium, ferrite, or samarium cobalt. These materials are known for their strong magnetic properties and durability.
Neodymium magnets are the most common type of magnets used in flat square magnets. They are incredibly strong and can hold a lot of weight. You can tell if a magnet is made from neodymium by looking at its color. Neodymium magnets are usually silver or gray in color and have a smooth, shiny surface.


Ferrite magnets, on the other hand, are made from a combination of iron oxide and other metals. They are less expensive than neodymium magnets but are also less strong. Ferrite magnets are usually black in color and have a rough, matte surface.
Samarium cobalt magnets are another type of magnet that is known for its high temperature resistance and strong magnetic properties. They are more expensive than neodymium and ferrite magnets but are also more durable. Samarium cobalt magnets are usually silver or gray in color and have a smooth, shiny surface.
If the magnet you're looking at is made from a different material, such as plastic or rubber, it's probably a fake. These materials do not have magnetic properties and cannot be used to make real magnets.
2. Test the Magnetic Strength
The next thing you need to do is to test the magnetic strength of the magnet. Real flat square magnets are very strong and can hold a lot of weight. You can test the magnetic strength of a magnet by using a small metal object, such as a paperclip or a key.
Hold the magnet close to the metal object and see if it attracts it. If the magnet is strong enough, it should be able to pick up the metal object easily. If the magnet is weak or does not attract the metal object at all, it's probably a fake.
You can also test the magnetic strength of a magnet by using a magnetic force gauge. A magnetic force gauge is a tool that measures the strength of a magnet. You can use a magnetic force gauge to compare the magnetic strength of the magnet you're looking at with the magnetic strength of a known real magnet.
3. Look at the Shape and Size
Real flat square magnets are usually very precise in shape and size. They have straight edges and corners and are uniform in thickness. If the magnet you're looking at has rough edges or corners or is not uniform in thickness, it's probably a fake.
You can also measure the size of the magnet using a ruler or a caliper. Real flat square magnets are usually very accurate in size and should match the specifications provided by the manufacturer. If the magnet you're looking at is significantly smaller or larger than the specifications provided, it's probably a fake.
4. Check the Surface Finish
The surface finish of a magnet can also tell you a lot about its authenticity. Real flat square magnets are usually very smooth and have a shiny surface. They do not have any scratches, dents, or other imperfections on the surface.
If the magnet you're looking at has a rough or dull surface or has scratches, dents, or other imperfections, it's probably a fake. These imperfections can indicate that the magnet was not made using high-quality materials or was not manufactured properly.
5. Look for a Brand Name or Logo
Real flat square magnets are usually manufactured by well-known companies that have a reputation for producing high-quality magnets. These companies usually put their brand name or logo on the magnet to indicate its authenticity.
If the magnet you're looking at does not have a brand name or logo on it, it's probably a fake. You can also check the packaging of the magnet to see if it has a brand name or logo on it. If the packaging does not have a brand name or logo on it, it's probably a fake.
6. Buy from a Reputable Supplier
One of the best ways to ensure that you're buying a real flat square magnet is to buy from a reputable supplier. A reputable supplier will only sell high-quality magnets that are made from real materials and are manufactured to strict standards.
