Attributes of Neodymium Block Magnets

Block magnets are the permanent magnets, very strong in nature. It is safe to use and of low cost as well. So it is

used in lots of application starting right from small children school science experiment to industrial and

technological application of the same.

It has been seen that when a Neodymium Block Magnet is suspended, with the help of a string, it just align well

to both the north and South Pole. It acts just like a compass which navigates the direction.

The Block magnets are featured with the strong magnetic field of permanent magnets. It will not subject to

demagnetized easily. These are the long-term Neodymium magnets, rectangular in shape which can retain the

magnetic power for a great span of period with no outside source of power supply.

Often it has been noticed that Block magnets are typically made of iron or steel, while they can be made

through any other permanently magnetized substance. But iron is the low cost material and so it is a wise and

easy choice.

The potent attribute of the Block magnet is that it is dipole. That means two distinct poles the north pole and the

south pole, which always direct to the north and south directions. The two Block magnets of opposite pole

attract each other, while the identical pole exerts each other with a magnetic force. It anyway you break a Block

magnet then you will get two different Block magnets having each with a north and South Pole.

Apart from all those application Block magnets also used in engineering application like for automation as well

as for the collection of loose metal materials. If a Block magnet is hanged in a string it naturally aligned to the

north and South Pole, just as a compass do.

The other feature associated with it that Neodymium Block Magnet usually poses moderate magnetic field

potency, which is sufficient enough for conducting small experiments. It has a magnetic strength, generally

approx to 100 gauss. These are the safe magnates; they never erase credit cards and not even cause you any

injury.

Basically you can see that all the Block magnets are made of iron and steel. In fact it can be made of any other

conducting material as well but iron is the low cost material so this material is widely used for the production of

Neodymium Block Magnet. However the when the metal passes through the Curie temperature it loses its

magnetic field. The Block magnet made of iron, can be demagnetized in a temperature near about 1,043 degrees

Kelvin, or 770 degrees Celsius.
