This 10x25mm rod permanent rare earth magnet packs a lot of power in a small space with enough pull at 10mm to be an effective stud finder.

Want to demonstrate eddy current braking? Drop this magnet down a 1/2" diameter copper or aluminum pipe & be amazed. Compare results with the 10x10mm, 10x15mm, 12.5x12.5mm or 12x25mm rod magnets. Or, go big with a 1" pipe & use the 25x20mm big disc magnet....bring something to read.

 

We have sold NdFeB magnets since 1996 and N42 grade since 2003, the best value for strength & temperature vs cost. Don't be fooled by claims of higher strength, N52, at lower cost.

We also provide complete Documentation including MSDS & ROHS; see below.

The Mark II Magnaprobe is an excellent tool for detecting magnetic fields & is must for any college or high school electricity & magnetism lab. See it in action below in our eddy current-drop tower braking simulation or read our blog Eddy Current Copper Tube Drop Tower Brake Test.

Even more impressive is the ultrasensitive Mark I Magnaprobe which responds to magnetic fields as weak as 0.3 gauss. A must if your cyclotron or particle collider is slightly off. In this instance, it was able to detect the eddy current in the simulation below at a distance of over 1m (3.3 feet)!
