How do you compare magnets?

The stronger a magnet, the larger its magnetic field. In other words, stronger magnets can attract metals from farther away. A bar magnet is under this paper, and iron filings have been sprinkled on top. You can see the shape of the magnetic field.

Which magnets are the strongest?

The strongest permanent magnets in the world are neodymium (Nd) magnets, they are made from magnetic material made from an alloy of neodymium, iron and boron to form the Nd2Fe14B structure.

What is the best type of magnet?

Neodymium Iron Boron (NdFeB) Magnets Neodymium magnets are rare-earth magnet materials with the highest magnetic properties. Composed of neodymium, iron & boron, these strong permanent magnets are the most powerful class of magnet materials commercially available today.

Which magnet is stronger N35 vs n50?

The difference between n35 and n50 magnets is the maximum strength that they can be magnetized to. The basic principle is that the higher the number the stronger the magnet. N35 is, therefore, the weakest and n50 the strongest of the neodymium magnets.

Which is the weakest magnet?

The weakest magnetic field measured is 0.5 femtotesla/√Hz, and was achieved by Dr. Sheraz Khan (Pakistan) and Dr. David Cohen (USA), at the Martinos Center, Massachusetts General Hospital, Charlestown, Massachusetts, USA, and was published in the Review of Scientific Instruments on 1 May 2013.

Which is the strongest natural magnet?

Rare earth magnets are alloys of these metals. A magnet made of neodymium, iron and boron is ridiculously strong (“the strongest magnet on earth,” in fact, according to Lewis).

Which is stronger N35 or N52?

An N52 magnet is approximately 50% stronger than an N35 magnet (52/35 = 1.49). In the US, it is typical to find consumer grade magnets in the N40 to N42 range. In volume production, N35 is often used if size and weight are not a major consideration as it is less expensive.
