N35 4mmx3mm Diametrically Magnetized Neodymium Disc Magnet Tiny Small Powerful NdFeB Round Magnets Nickel-Plated radial magnetization for sale
This rod is the only rod magnet that is diametrically magnetised. This means that these rods will not lay endways on each other, but rather sideways, like fish sticks. This allows for interesting experiments, but is rather unusual in everyday life.
