A neodymium disc magnet weighing only 2 grams can lift a steel block weighing over 2,000 grams! Neodymium magnets emit deep magnetic fields to attract ferrous items and other magnets from impressive distances.
How strong is a neodymium magnet?
How Strong Are Neodymium Magnets? Very strong. They will amaze you! A 2-gram (0.07 ounce) neodymium magnet that measures 8 millimeters (0.315 inches) in diameter and 5 millimeters (0.197 inches) long generates a force of over 1700 grams (3.75 pounds).

Is n52 the strongest magnet?
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. … There is a premium on the price of the highest grade magnets so it is more common to see N48 and N50 magnets used in production versus N52.
Why are neodymium magnets illegal?
The Consumer Product Safety Commission has just banned the sale of Buckyballs, those magic magnets that can be shaped any which way, because the balls are a serious health hazard for children. It’s the first stop-sale order by the CPSC in 11 years.
Do Neodymium magnets break easily?
Neodymium magnets are brittle – and can easily shatter and break. Neodymium magnets are brittle and will peel, chip, crack or shatter if allowed to slam together, even from just a few inches apart. Despite being made of metal and coated with a shiny nickel-plating, they are not as hard as steel.
How strong is a 1 Tesla magnet?
Measuring Magnetic Strength
One tesla equals 10,000 gauss. Magnometers, gaussmeters or pull-testers are all used to gauge the strength of a magnet.
Do magnets get stronger when stacked?
By adding one magnet on to the other, e.g. stacking, the stacked magnets will work as one bigger magnet and will exert a greater magnetic performance. As more magnets are stacked together, the strength will increase until the length of the stack is equal to the diameter.
Why is it called a rare earth magnet?
SmCo and NdFeB magnets are called “rare earth” because they are made from the rare earth, or lanthanide series, of the periodic table of elements. SmCo magnets were developed in the 1970s and were the first of the rare-earth magnets to be produced.
What is the best grade of neodymium magnets?
The highest grade of neodymium magnet currently available is N52. Any letter following the grade refers to the temperature rating of the magnet. If there are no letters following the grade, then the magnet is standard temperature neodymium. The temperature ratings are standard (no designation) – M – H – SH – UH – EH.
Can Neodymium magnets damage cell phones?
The short answer is, if the magnet is big enough and strong enough it could damage your device, and not just by dropping the magnet on it! … However, modern smartphones use LCD screens which are not generally susceptible to magnets, hurrah!
Can you cut Neodymium magnets?
CUTTING OR DRILLING NEODYMIUM MAGNETS
Magnets are sintered and are therefore extremely hard and brittle. You should never attempt to cut or drill into a magnet unless using diamond tooling and coolant as the dust can be highly flammable.
What are strongest magnets?
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.
How strong is a grade 5 magnet?
Commercially available neodymium magnets range from N35 to N55 grade; the number after the letter ‘N’ represents the magnet’s maximum energy product. So, you guessed it, an N55 grade neodymium magnet is approximately 50% stronger than an N35 magnet of the same size.
What is the strongest rare earth magnet?
