How Magnets Work Underwater

Magnets maintain their magnetic properties when submerged underwater. Since water is nearly non-magnetic, it does not affect the magnetic field. Consequently, the same principles that govern magnets in air hold true underwater. This consistent performance makes our magnets ideal for various marine applications, ranging from securing equipment in subsea operations to serving as anchoring points for divers or remotely operated vehicles (ROVs).

Testing Magnet Functionality Underwater

Testing a magnet’s functionality underwater is straightforward. By bringing two magnets close together underwater, one can readily observe that they attract just as they would in air. Nonetheless, it is essential to dry them after testing to prevent rust—unless they are constructed from stainless materials. Fortunately, our magnets are made of corrosion-resistant stainless steel and have been thoroughly tested.

The Importance of Using Durable Magnets Underwater

For underwater applications, durability is as critical as functionality. At Blumags, we ensure that all our marine magnets—including our tactical editions—are fabricated from corrosion-resistant stainless steel and incorporate a robust neodymium core. These design features guarantee long-lasting performance and reliability even in the harshest marine environments. For instance, we deployed one of our magnets on the sunken Blücher ship in Oslofjorden, where it remained fully functional for over two years. Learn more about our involvement with Blücher here.

Conclusion

Whether for professional marine operations or casual underwater exploration, magnets serve as powerful and reliable tools. At Blumags, our underwater magnets are engineered to endure the most challenging marine conditions, delivering exceptional performance whenever and wherever required.
