A few "strong" facts about our super magnets:
The strongest ring magnet: Ideal for "fishing" ferromagnetic objects. It will easily pull your bike out of the lake, for instance.
Our so-called "death magnet": A compact block magnet with an adhesive force of 100 kg.
The "strongest" in our web shop: The block magnet MONOLITH with a strength of approx. 200 kg.
Before using any of our super magnets, please read the safety tips to avoid hazards and injuries.
