How does the thickness of the steel shell affect the magnetism of pot magnets?

     Pot magnets are typically magnet assemblies with powerful sintered NdFeB magnets embedded in a durable steel housing or tank.The specific structure consists of three parts: the magnet is a neodymium magnet (which can also be ferrite); the shell is generally a steel shell (the production process of the steel shell is divided into two types: turning and stamping. For uniform sizes, the precision of turning processing higher); the gasket is made of plastic (also available in epoxy resin, brass, etc.).

     Permanent magnets are very brittle, easy to break, and have limited magnetic force. The steel shell provides a safe place for powerful round/rectangular permanent magnets to protect the magnets. It can also affect the magnetic properties of the magnets, such as providing magnetic shielding. Magnetism focuses on only one facet and intensifies them.

     But will different thicknesses of steel shells bring the same effect? Next we will talk about how the thickness of the outer steel shell affects the magnetic properties of the pot magnet.

     A thicker steel shell can increase the shielding effect on the magnetic field and hinder the penetration and induction of the magnetic field. This may weaken the pot magnet's magnetic field strength and force, as part of the magnetic field is absorbed or deflected by the steel shell.

     On the other hand, a thinner steel shell may allow more magnetic fields to pass through and reduce the shielding effect on the pot magnets. This may increase the magnetic field strength and magnetic force of the pot magnet.

     Therefore, the thickness of the steel shell can be selected according to the specific application requirements. Thicker steel shell provides higher shielding effect and is suitable for situations where magnetic field interference needs to be reduced. Thinner steel shells are more suitable for applications requiring greater field strength and magnetic force. When designing a pot magnetic system, the balance between magnetic field shielding and magnetic output needs to be considered comprehensively to meet the needs.Welcom to consult with professional ndfeb magnet supplier.
