What does grade n42 magnet mean? The grade N42 means a neodymium magnet has a maximum energy product of 42 MGOe. It refers to the maximum magnetic energy that the material can be stored. It can be showed by the magnet’s Demagnetization Curve, or BH Curve – the strongest point is (BH)max.
Are N42 magnets strong?
N42 neodymium magnets are powerful, versatile magnets that are suitable for almost any common application. It is only when extreme levels of strength in extremely small sizes are required that we recommend selecting an N50 or N52 magnet instead.
Is N42 stronger than N52?
You can get the same strength as an N52 magnet by using a slightly larger N42 magnet. If you have slightly elevated temperatures, in the 140°F to 176°F range (60°C -80°C), N42 magnets might actually be stronger than N52. This is especially true if your magnet shape is very thin.
How strong is a N42 neodymium magnet?
This N42 disc magnet measures 0.100″ in diameter and 0.200″ in thickness or (2.54 mm Dia. x 5.08 mm THK) with an approximate pull force of 1.75 lbs (794 g).
What does N42 mean on a magnet? – Related Questions
What is the strongest grade of magnet?
What is the strongest type of magnet? Neodymium magnets are the strongest magnets in the world. 14.
Which is strongest magnet?
The strongest permanent magnets are neodymium (Nd) magnets. They are made from an alloy of neodymium, boron and iron to form Nd2Fe14B structure. Neodymium is a rare earth element.

How much weight can a N52 magnet hold?
This magnet can hold up to 10 lbs under ideal conditions, and their grade N52 neodymium material makes them the strongest magnets of their size commercially available.
Is N52 the strongest neodymium magnet?
Neodymium is the strongest rare earth magnet material, and N52 is among the highest grades of neodymium; consequently, N52 magnets are some of the strongest magnets on the planet. The number abbreviation, N35, N42, N52, or N55 for example, indicates the strength, or energy product, of the magnet grade.
Which is stronger N35 or N52 magnet?
Manufacturing Differences Between N35 and N52
Yet, N52 magnets are 50% stronger than N35 magnets (52/35 = 1.49), so we want to identify them. Nd2Fe14B or Neodymium-Iron-Boron magnets can be sintered or bonded.
What is the 2 strongest magnet?
The second strongest magnets are neodymium magnets. These are made from rare earth materials, which are the strongest in the world. Neodymium magnets are available in a wide variety of sizes, shapes, and grades, and can be used in any kind of environment.
What magnets does Tesla use?
With a market capitalization of almost $1 trillion, Tesla is one of the most valuable automobile manufacturers globally. It uses lithium – battery – and boron – neodymium magnets – to deliver alternative energy sources and boron to provide a lighter, more muscular frame.
Does bigger magnet mean more power?
The bigger the magnet is, the more reactive and powerful the driver will be. A powerful permanent magnet also translates to a more sensitive loudspeaker. Neodymium is a powerful natural magnet. A small piece of neodymium has stronger electromagnetic currents than an inferior magnet of the same size.
How can you tell if a magnet is strong?
The maximum energy product of a magnet is measured in Mega Gauss Oersteds (MGOe). This is the primary indicator of a magnets ‘strength’. In general, the higher the maximum energy product value, the greater the magnetic field the magnet will generate in a particular application.
What are the 3 types of magnets?
There are three types of magnets: permanent magnets, temporary magnets, and electromagnets.
Can you make magnet stronger?
Expose it to Cold
By exposing the weakened magnet to freezing temperatures, the molecules in the magnet will have less kinetic energy and will slow down. This decreased movement will allow the atoms to line up better creating a more concentrated magnetic field which will result in a stronger magnet.
What increases magnetic strength?
To recharge a magnet, find a very strong magnet and rub it across the weakened magnet repeatedly. This will realign the magnetic domains in the weak magnet. Another way to make weak magnets stronger is by stacking them. This can be tough, as magnets attract each other in opposite directions, which can weaken them.
Do magnets lose their strength over time?
So any magnet will slowly weaken over time. However, heating or dropping a magnet will hasten this process. That is why your physics teacher glared at you when you carelessly knocked a magnet off the lab desk.
