When it comes to magnets, many people mention their magnetic strength. So, are rubber soft magnetic strips (or sheets) particularly strong? Below, Fu from Karichi will answer this question for you.
Rubber soft magnetic strips generally have relatively weak magnetic properties; they belong to the category of ferrites with low magnetic performance, with a magnetic energy product of approximately 0.8–5.2 MGOe. Compared to other materials, such as neodymium-iron-boron magnets and ferrite magnets, the magnetic properties of rubber soft magnetic strips are significantly weaker.

How many gauss do rubber magnetic strips have?
The magnetic field strength of rubber soft magnetic strips is usually measured in gauss (Gauss). However, the magnetic field strength of rubber soft magnetic strips varies depending on factors such as the manufacturing materials, dimensions and magnetisation method. Generally speaking, the magnetic field strength of rubber soft magnetic strips is typically low, ranging from tens to hundreds of gauss, with the specific value depending on the strip’s design and material.
Soft magnetic strips are primarily used to provide a mild holding force in specific applications, such as securing lightweight objects or providing a gentle magnetic hold. If a magnet with strong magnetic properties is required, options include neodymium rare-earth magnets, samarium-cobalt magnets, ferrite magnets and others.
