A rod magnet has a classic cylindrical design that many of us remember from school. Its diameter is generally smaller than its height, however, we also depict magnets that have the same diameter and height. In our online shop, you can buy strong, round rod magnets made of neodymium. Even small magnets feature a very high adhesive force but can be easily separated thanks to their thin frame. Depending on what you need them for, you can order magnetic rods in different heights and diameters.
Do you need red-green magnetic rods for school use instead? We also show them in this group. The whole selection of red-green magnets can be found under Experiments & School.
Buy rod magnets - large selection, inexpensive prices
Just like any other magnet, the adhesive force of rod magnets depends on their measurements. The larger height and diameter, the stronger they are. In our online shop, you can find a big selection of different designs. Utilise our filter to find the right rod magnets for your project. Block pricing is available for various products. The larger the order quantity, the lower the per-unit price.
Direction of magnetisation of rod magnets
Axial magnetisation: Most of the magnetic rods in our assortment are axially magnetised, which means the north and south pole are located at the ends of the rod. The magnetisation is therefore similar to that of a compass needle. The rod magnet does not have any magnetic pull in the middle.
Diametrical magnetisation: Some of our products are diametrically magnetised, e.g. article S-04-10-DN. These rod magnets have their north and south pole on each of the long sides, ergo they are located "left" and "right" and not as with axially magnetised rods on the "top" and "bottom". While axially magnetised rods can be lined up at their circular areas, diametrically magnetised rods line up next to each other like fish sticks. They are good accessories for interesting experiments with which you can create impressive magnetic sculptures.
Practical applications for rod magnets
Rod magnets work well on a whiteboard, magnetic board or fridge if you want to hang up photos, notes, etc. Thanks to their oblong shape they are easier to grasp than flat disc magnets, which makes moving around objects easier.
Neodymium rod magnets are also suitable to countersink boreholes, which allows for several objects to be combined magnetically or to create magnetic clasps for jewellery, wooden boxes, etc.
Would you like to execute experiments around the topic of magnetism in school or at the university? Then, long rod magnets are the right choice. They work well if you want to make magnetic field lines visible with iron filings - a classic among physics experiments.
With rod magnets and steel spheres you can make new magnetic sculptures - according to our customers this may lead to a certain amount of addiction!
Another practical application in workshops is collecting and storing fo screws and metal filings, given that they are made of iron or steel.
This list is of course far from comprehensive - see for yourself about the multi-functionality of rod magnets in our customer application section.
What happens when you break a rod magnet?
If a rod-shaped permanent magnet with north and south pole at the circular areas was broken in half, both parts would have a north and south pole. If you broke it again, all other parts would still have both different poles.
Where is the strongest spot on a rod magnet?
The adhesive force of any magnet is the strongest at their poles. An axially magnetised rod is strongest at its ends because the magnetic field lines are most concentrated there. A rod magnet has practically no magnetisation in the middle.
