About the Product

Neodymium tube magnets provide an ID/OD geometry with defined wall thickness for shafts, pass-through fasteners, and flow-through fixtures. Axial magnetization through thickness yields a clean annular field; diametrical options are available for certain sensing applications. Tight ID/OD and length tolerances support press-fits and concentric mounting with minimal runout. Use the calculator to model attraction versus steel and air gap, then size grade and coating using the material data to meet field and temperature targets.

tube magnets in the research lab!

I needed a tube magnet with an ID of a maximum of 1mm. I could not find it anywhere else except here. In my research, I needed to stimulate a flow through a pipe by a strong magnetic field. So, I needed a tube magnet with an ID close to the OD of my tube as much as possible. However, it would have been perfect if I was received the map of the magnetic field in the axial and diametrical axis. Now, I have to prepare such a map by sophisticated software like COMSOL. By the way, when I started the experiment by these magnets, I was worried about the accuracy of dimensions. I measured that, and it is accurate enough! Also, I align the diametrical tube magnet along the axial axis and they are stable ( I mean they could have repel eachother because they designed to attract each other when they become arranged next to each other not on each other), which means the magnetization of N and S pole are perfectly accurate.
