We are proud to present the by far strongest neodymium magnet in our online shop! With its unbelievable adhesive force of 400 kg, this fishing magnet really does break all records. To call it a heavyweight is an understatement. Definitely not a toy for children and not recommended for beginners.
In contrast to regular retrieving magnets, this magnet is magnetic on both sides. That is to say, the underside, as well as the top, has an adhesive force of 400 kg thanks to the steel casing. The principle is the same as with our pot magnets: Because the two built-in ring magnets are encased in steel, with direct contact, their forces are focused towards the holding surfaces. This results in a particularly high magnetic adhesive force at the contact surfaces.

This retrieving magnet has another great feature besides its enormous adhesive force: It contains two inner threads to hold eyebolts with M12 thread. One such eyebolt is included in the delivery. When screwing in the bolt, make absolutely sure that it is securely fastened. You can order a suitable rope separately in our shop. Matching accessories such as ropes and storage bags can be found under links below.

Please note: The fishing magnet 400 will only reach its full force if the surface is flat, smooth and thick enough. In addition, the magnet must make direct and full contact with it. If all of these conditions are not met, a pot magnet may have significantly less adhesive force than, for example, a ring magnet with the same or even weaker adhesive force. Furthermore, the full adhesive force only applies if you pull the magnet off the surface in a perpendicular direction (i.e. at a 90-degree angle to the surface). The adhesive force is considerably lower when you pull the retrieving magnet off the surface sideways. You can find more information about this topic on our FAQ page "adhesive force vs shear force".

Included in the delivery: Fishing magnet and eyebolt M12.

Please note

  • Magnets are not a toy, and careless handling can lead to injuries! So please make sure you familiarise yourself with the safety tips for neodymium magnets.
  • Be extremely careful in areas where there may be unexploded bombs!
  • If you really do find a treasure, you are usually not entitled to keep it - follow the legal regulations!
  • You can find additional important information in our FAQ about magnet fishing
