How to Choose Strong Bar Magnets

Material

Business owners should pay special attention to the magnet's material. Neodymium magnets are the strongest in the world and known for their exceptional strength. They are small in size but very powerful. This magnet is also brittle and may break if mishandled. Nickle should be used to coat this magnet so it does not rust. There is also the aluminum nickel cobalt (alnico) magnet, which can withstand high temperatures. There are also ceramic or ferrite magnets, which are tough and can withstand harsh conditions.

Thickness

When choosing a bar magnet, business owners should consider the thickness or depth of the magnet. Generally, the thicker the bar magnet, the stronger it will be. This is measured in magnetic pull strength. Buyers should choose strong magnets that have a thickness proportionate to their bar length.

Coating

Business owners should ensure that the strong magnets they purchase have the right coating. This will be especially important for retailers dealing with customers who will have to handle the magnets. Ideally, magnet coatings should be smooth to protect the hands of the handlers from cuts. The coating also protects the magnet from rust. Common coatings include copper, ceramic, ferrite, and chromium. If the magnets are to be used in a humid area, business owners should opt for coated magnets.

Business use

Different types of bar magnets are suitable for different types of businesses. Bar magnets are ideal for businesses that conduct science projects. They can also be used by construction companies that need to move metal objects. Hardware stores can also sell these magnets to people who need them for small DIY projects.
