Plastic Capped Magnets in Ferrite, Round Red

Plastic Capped Magnets in Ferrite, Round Red, Plastic Capped Ferrite Magnet, Colorful Notice Board Marker Magnets in ABS Plastic

Plastic Capped Magnets – These colourful and stylish magnets are attractive in every sense of the word; they’re the perfect partner for any noticeboard and won’t ever let you down. Here, you’ll find ferrite magnets for regular whiteboards, glass wipe boards or maybe even magnetic noticeboards themselves.

Red Round Plastic Coated Ceramic Magnets for Office or Fridge, Small plastic-coated magnets

Small plastic-covered magnets made of ferrite. Diameter 10 mm up to 40mm,  0.07g up to 1.65g holding force. Inside the plastic casing with a diameter of 10 mm lies a small but powerful ferrite magnet, which provides a safe position. In the classic round shape of this is quite small magnetic reside a surprisingly powerful magnet, which is not commonly available.

1. What are neodymium magnets? Are they the same as “rare earth”?
Neodymium magnets are a member of the rare earth magnet family. They are called “rare earth” because neodymium is a member of the “rare earth” elements on the periodic table. Neodymium magnets are the strongest of the rare earth magnets and are the strongest permanent magnets in the world.

2. What are neodymium magnets made from and how are they made?
Neodymium magnets are actually composed of neodymium, iron and boron (they are also referred to as NIB or NdFeB magnets). The powdered mixture is pressed under great pressure into molds. The material is then sintered (heated under a vacuum), cooled, and then ground or sliced into the desired shape. Coatings are then applied if required. Finally, the blank magnets are magnetized by exposing them to a very powerful magnetic field in excess of 30 KOe.

3. What dose N35,N38,N40,N42,N45,N48,N50,N52 grade mean?
Neodymium magnets are graded by the maximum strength they can be magnetized to. The higher the number the stronger the magnet is, however the higher the number the more brittle the magnet becomes as well.
N52 Neodymium (more precisely Neodymium-Iron-Boron) magnets are the strongest permanent magnets in the world.

4. How is the strength of a magnet measured?
Gaussmeters are used to measure the magnetic field density at the surface of the magnet. This is referred to as the surface field and is measured in Gauss (or Tesla). Pull Force Testers are used to test the holding force of a magnet that is in contact with a flat steel plate. Pull forces are measured in pounds (or kilograms).  Round Ferrite Plastic Magnets White

5. How is the pull force of each magnet determined?
All of the pull force values we specify have been tested in our laboratory. We test these magnets in two different configurations. Case 1 is the maximum pull force generated between a single magnet and a thick, ground, flat steel plate. Case 2 is the maximum pull force generated with a single magnet sandwiched between two thick, ground, flat steel plates. Case 3 is the maximum pull force generated on a magnet attracted to another magnet of the same type.
