    Quite often gauss magnetic strength is misquoted or exaggerated. One common misunderstanding is the difference between what is called the Manufacturer's Rating and the actual Surface Gauss Rating of a magnet,. The Manufacturer's Rating is much higher than the Surface Gauss, and represents two different ways of measuring the strength.Manufacturer's Rating: Technically this is called the Magnetic Remanence (Br) of the magnetic material and is a property of the magnet when measured i...

    Magnetic Poles are the surfaces from which the invisible lines of magnetic flux emanate and connect on return to the magnet. All magnets have two poles, a North pole and a South pole. By convention, we say that the magnetic field lines leave the North end of a magnet and enter the South end of a magnet. This is an example of a magnetic dipole ("di" means two, thus two poles). If you take a bar magnet and break it into two pieces, each piece will again have a North pole and a So...

    You can't tell by looking. You can tell by placing a compass close to the magnet. The end of the needle that normally points toward the North pole of the Earth would point to the South pole of the magnet.

  • A:

    There are 2 types of magnets: permanent magnets and electro-magnets.Permanent magnets emit a magnetic field without the need for any external source of power. Electro-magnets require electricity in order to behave as a magnet.There are various different types of permanent magnet materials, each with their own unique characteristics. Each different material has a family of grades that have properties slightly different from each other, though based on the same composition.

    Rare Earth magnets are magnets that are made out of the Rare Earth group of elements. The most common Rare Earth magnets are the Neodymium-Iron-Boron and Samarium Cobalt types.20.Which are the strongest permanent magnets?The most powerful permanent magnets available today are the Rare Earths. Of the Rare Earths, Neodymium-Iron-Boron types are the strongest. However, at elevated temperatures (of approximately 150 C and above), the Samarium Cobalt types can be stronger that the Neodymium-Iron-B...

    Most modern magnet materials have a "grain" in that they can be magnetized for maximum effect only through one direction. This is the "orientation direction", also known as the "easy axis", or "axis".Unoriented magnets (also known as "Isotropic magnets") are much weaker than oriented magnets, and can be magnetized in any direction. Oriented magnets (also known as "Anisotropic magnets") are not the same in every direction - they have ...

  • A:

    Not easily or safely. Neodymium sintered magnets behave like a ceramic. They have a tendency to crack and chip when drilled. Additionally, the powder produced when machining these magnets is flammable. Lastly, machining causes heat to build up in the magnet which may result in it being demagnetized. Most likely, a drilled or machined Neo magnet will be made unusable by the process due to breakage, cracking or heat damage.

  • A:

    Yes, if heated beyond 176 degrees Fahrenheit (80 degrees Celsius) the magnets will quickly loose their magnetic properties. Sustaining these temperatures for a length of time or heating the magnet significantly higher than this will permanently demagnetize it. Other types of magnets such as Samarium-Cobalt have higher heat resistance. There are also other types of Nd-Fe-B magnets that are not as susceptible to heat induced flux degradation.

  • A:

    No, unless you have an internal medical device such as a pacemaker that would be affected by a strong magnetic field. However, Neodymium magnets are very strong and should be handled with care. These magnets can pinch if allowed to come together against the skin and larger magnets are capable of breaking bones. For this reason, children should not be allowed to play with the larger magnets.

  • A:

    Diametrically magnetized cylinder magnets have the poles (attraction) on the curved sides instead of on the flat ends.
