Outdoor Magnet General Information

Below are some common questions and answers about using magnets outside.

Can I use magnets outside/outdoors?

Yes, neodymium magnets can be used outdoors. For outside applications, it’s best to use waterproof or water resistant outdoor magnets which are designed for use outside and are fully encased in protective coatings such as rubber coated, plastic coated or stainless steel to prevent wear, oxidation, and surface damage. Neodymium magnets without a protective coating may rust, corrode or lose strength when exposed to moisture and air.

Do magnets work in cold weather?

Yes, neodymium magnets work well in cold weather, including in snow and freezing temperatures, and can even become stronger as temperatures drop. They perform reliably in temperatures as low as -40°C to -60°C (-40°F to -76°F). Although magnetic strength decreases more rapidly below -125°C (-193°F), neodymium magnets still retain significant magnetic force. Since temperatures this extreme are rarely encountered in everyday environments, neodymium magnets remain the best choice for almost all cold-weather outdoor applications.

Discover how cold and hot temperature fluctuations can affect magnets in our How Temperature Affects Magnets blog post.

Do magnets work in hot weather?

Yes, neodymium magnets work in hot weather, but high heat can cause them to become weaker temporarily. If they exceed specific temperature thresholds, the magnets can be permanently damaged.

All our outdoor neodymium magnets have a max operating temperature of 176°F (80°C). Temperatures below this limit may cause a temporary loss of strength that returns after cooling. Exceeding the limit can cause permanent demagnetization and reduced strength.

When using magnets in very hot climates or regions with prolonged sun exposure, it is important to consider the magnet’s maximum operating temperature. Outdoor surfaces such as steel roofs, vehicles, metal walls, and equipment can become significantly hotter than the surrounding air temperature when exposed to direct sunlight. For outdoor applications with extended sun and UV exposure, choosing a magnet with an appropriate temperature rating can help ensure reliable long-term performance.

Can I use outdoor magnets on my gutters?

Yes, magnets can be used on gutters for projects such as hanging lights, flags, decorations or other objects. If you have steel gutters, the magnets will stick directly to the gutters. If your gutters are aluminum, which is non-magnetic, you'll need to use a second magnet on the opposite side of the gutter so the two magnets attract to each other through the gutter.
