What is the magnetic flux density of a 6x2mm disc magnet?

Hey there! As a supplier of 6x2mm disc magnets, I often get asked about the magnetic flux density of these little guys. So, I thought I'd take the time to break it down for you and give you a better understanding of what's going on with these magnets.

First off, let's talk about what magnetic flux density actually is. In simple terms, magnetic flux density (also known as magnetic induction or magnetic field strength) is a measure of the strength of a magnetic field at a particular point. It's usually denoted by the symbol B and is measured in teslas (T) or gauss (G), where 1 T = 10,000 G.

Now, when it comes to our 6x2mm disc magnets, the magnetic flux density can vary depending on a few factors. One of the most important factors is the material the magnet is made of. Most of the 6x2mm disc magnets we supply are made of neodymium, which is a type of rare - earth magnet. Neodymium magnets are known for their extremely high magnetic strength compared to other types of magnets like ferrite or alnico.

The grade of the neodymium also plays a big role. Neodymium magnets come in different grades, such as N35, N42, N52, etc. The higher the grade number, the stronger the magnetic field the magnet can produce. For example, an N52 grade neodymium 6x2mm disc magnet will have a higher magnetic flux density than an N35 grade one.

Another factor that affects the magnetic flux density is the distance from the magnet. The magnetic field strength decreases as you move further away from the magnet. This relationship follows an inverse - square law, which means that if you double the distance from the magnet, the magnetic flux density will decrease to one - fourth of its original value.

So, what's the typical magnetic flux density of a 6x2mm disc magnet? Well, it's a bit tricky to give an exact number because of the factors I mentioned above. But generally, for an N42 grade 6x2mm neodymium disc magnet, the magnetic flux density at the surface of the magnet can be around 0.5 - 0.6 teslas or 5000 - 6000 gauss.

Now, you might be wondering why the magnetic flux density matters. Well, it's crucial in a lot of applications. For example, in electronics, the magnetic field strength of a magnet can affect the performance of sensors, actuators, and motors. If you're using a 6x2mm disc magnet in a magnetic sensor, a higher magnetic flux density can lead to a more sensitive and accurate sensor.

In the field of jewelry making, magnets are often used to hold pieces together. A magnet with a higher magnetic flux density can provide a stronger hold, ensuring that the jewelry stays intact.

Another popular size is the 5x3mm Neodymium Magnets, which are also great for various projects.

When it comes to measuring the magnetic flux density of our 6x2mm disc magnets, we use specialized equipment like a gaussmeter. This device can accurately measure the magnetic field strength at different points around the magnet. We make sure to test each batch of magnets to ensure they meet the required standards.

If you're thinking about using 6x2mm disc magnets in your project, it's important to consider the magnetic flux density based on your specific needs. If you need a stronger magnetic field, you might want to go for a higher - grade neodymium magnet. But keep in mind that higher - grade magnets can also be more expensive.

In addition to the magnetic flux density, there are other important properties of these magnets that you should be aware of. For example, the coercivity of a magnet is a measure of its resistance to demagnetization. Neodymium magnets generally have a high coercivity, which means they can maintain their magnetic field even when exposed to external magnetic fields or high temperatures to some extent.

The remanence of a magnet is another important property. It's the magnetic flux density that remains in the magnet after it has been magnetized in a strong external magnetic field. A higher remanence value indicates a stronger permanent magnetic field.
