- 0.50″ Diameter x 0.38″ Height, 1.5 pounds pull capacity
- Poles each occupy a side of the end of the magnet face and are separated by a groove
- Made from a single piece of material so don’t suffer from differential expansion or contraction and are therefore more suited to some higher temperature applications than pot magnets
- Not as powerful as the equivalent pot magnet but have a greater depth of field (the distance that the magnet can attract over)
