How strong is N40 magnet?
Product Details. This N40 disc (cylinder) magnet measures 0.125″ in diameter and 0.675″ in thickness (3.18 mm Dia. x 17.15 mm THK) with an approximate pull force of 7 lbs. (3.18 kg).
What is an N40 magnet?
Strong Neodymium Magnet Grade N40, stronger than N38 and N35. Br Max: 12900 gauss. Neodymium magnets (also known as Neo, NdFeB, NIB or super magnets) , a type of rare earth magnets, are permanent magnets made from neodymium, iron, boron and other minor elements.
What is the strongest neodymium magnet?
N52 grade
Strongest: N52 grade is the strongest and the rarest neodymium magnet type among the existing ones. Neodymium magnets of this grade ensure maximum sticking while being characterized with minimum sizes. Less than 5 % of all neodymium magnets produced all over the world belong to this grade.
Which is stronger N42 or N52 magnet?
The grades of neodymium magnets that we normally carry are N42, N48 and N52, a rating that is generally measured in Tesla metrics or units of Gauss Oersted (MGOe). A magnet of grade N42 has a Maximum Energy Product of Gauss 42 MGOe, while an N52, at 52 MGOe would be incrementally stronger.
Does stacking Neodymium magnets make them stronger?
Yes, stacking multiple magnets together can make them stronger. Two or more magnets stacked together will exhibit nearly the same strength as a single magnet of the combined size.
Can Neodymium magnets pick up coins?
Obtain a rare-earth magnet, such as a neodymium magnet. Due to its strength, the rare-earth magnet can pick up a chain of coins, with each coin attached to the other in a chain formation.
Is playing with magnets bad for you?
Generally speaking, magnets below 3000 Gauss (magnetic field unit) are basically harmless to the human body, while magnets with magnetic field strength above 3000 Gauss are harmful to the human body. Although some magnets are harmful to humans, this negative effect is also negligible.
