Rare Earth Round NdFeb Magnets Permanent Super Strong Disc Neodymium Magnet for Sale

This disc neodymium magnet is made of strongest grade N35 rare earth magnetic material and coated with Ni+Cu+Ni triple layer. This disc neodymium magnet has innumerable applications for business and home, such as kitchen knife holders. Our Neodymium magnets are commonly used in creative applications such as models and theatre design, furniture making, exhibition stands and packaging. They also have many uses in engineering and manufacturing where compact size and maximum strength are required.

Features

They are axially magnetized so the north and south poles are on the flat surfaces, and the red line on one side of the magnet denotes which side the north pole is on. Neodymium magnets are unique because of their extreme resistance to demagnetization and will only lose their magnetism if they're heated above 176 degrees fahrenheit.

FAQ: 

Q1. Which is stronger N35 or N52 magnet?

A1. There are eight different standard grades of neodymium magnets typically used in commercial applications today ranging from N35 to N52. Neodymium magnets are graded by their maximum energy product (BH)max with N52 grade neodymium providing the greatest magnetic performance and N35 being the weakest.

Q2. What are neodymium disc magnets for?

A2. In the field of information technology, neodymium magnets are particularly used in hard disc drives, mobile phones, video and audio systems of television. Neodymium magnets are also commonly used in magnetic separators, filters, ionizers, in production of on–off buttons, safety sector and security systems.

Q3. Does neodymium lose their strength?

A3. Like all magnets, neodymium magnets will eventually lose their strength over time, but this process is slow and can take many years or decades.

Q4. What makes neodymium stronger?

A4. Neodymium magnets are so strong because of their high resistance to demagnetisation (coercivity) and their high levels of magnetic saturation allowing them to generate large magnetic fields. A magnet's strength is represented by its maximum energy product value (BHmax) which is measured in Mega Gauss Oersteds (MGOe).

Q5. What happens if you cut a neodymium magnet?
A5. 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.
