What Type of Magnet is the Strongest?

Are you searching for a magnetic material with more punch? Look no further than neodymium magnets - part of rare earth magnets and known for being among the strongest commercially available magnets. Neodymium magnets also possess extreme durability and resistance to demagnetization, making them perfect choices for applications which need strength in a compact space.

Neodymium magnets produce powerful magnetic fields due to their atomic structure. Neodymium and samarium are both ferromagnetic elements with inherent magnetic properties; when combined with iron and boron to form an alloy that's then press-sintered, its maximum energy product value becomes extremely high - giving the magnet its strong magnetic pull.

To ascertain the strength of a magnet, its maximum energy product value must be understood. This value can be calculated by multiplying its remanence and coercivity values together; remanence measures how much magnetism remains after magnetic fields have been removed, while coercivity reflects resistance to demagnetization. A higher maximum energy product value indicates stronger magnets.

At its maximum strength, neodymium magnets reach 52 mega-gauss-oersteds (MGOe). This means they can sustain pull forces of up to 330 pounds - providing incredible amounts of pulling power for various uses.

Neodymium magnets may have incredible strength, yet can still be damaged by excessive heat or sudden temperature shifts. Therefore, it is wise to handle them carefully and limit exposure to extreme temperatures or direct sunlight.

Neodymium and samarium magnets should also be kept out of reach of children for safety. Constructed from rare earth materials, they can pose health hazards if swallowed whole; their small pieces could even cause choking or blockages in throat and stomach if consumed accidentally.

Neodymium magnets may be the strongest commercially available magnets, but other types of permanent magnets offer comparable magnetic strength. One example is Samarium Cobalt which may offer advantages in terms of durability and corrosion resistance over their neodymium counterparts. Another alternative is Alnico which is made up of strontium carbonate and iron oxide hard magnets with lower magnetic strengths than their Neodymium counterparts but cannot degrade as easily and can withstand temperatures up to 400F without degrading as easily.

Neodymium magnets are both strong and cost-effective permanent magnets. They're the most commonly used permanent magnet and can be found across industries; making them an effective, safer alternative to adhesives and fasteners. But it should be remembered that these magnets should not be considered toys; breaking apart may result in choking hazards or blockages in children's throats or stomachs, not to mention they pose a potential fire hazard that should be handled carefully.
