Can we send magnets by post?

We can send magnets by postal mail, as long as we are very cautious since the magnetic field can transfer the packaging and the content of the packages that are close to it can be affected and damaged. In the same way, it can disrupt sorting systems and can be lost due to its attraction force being trapped in a metallic object. This is why if we need to send any magnetic element we must take care of the packaging.

Magnet shipments can be of two types:

• Air transport= Air transport is based on a type of transportation that allows parcels to be moved over long distances at a faster rate.
• Ground transport= Ground transport is usually used for short-distance shipments, being the most economical and practical transport as long as they are sent over short distances. shipped over short distances.
• Maritime transport= Maritime transport allows us to send large quantities of various dimensions at a very economical cost.

Regardless of the type of transport used, each country has its own rules.

How can we send a magnet by mail?

When sending magnets by postal mail you must take into account several factors, in addition to reducing the magnetic field. The factors we must take into account are:

1. The distribution of the magnets inside the package:

If we want to send more than one magnet, we must distribute them in such a way that half of the magnets are parallel to the other half, in other words, the poles must be in opposite directions to each other.

In the case that we only want to send two magnets, they cannot be placed parallel to each other but must be placed on a metal sheet, in the same way, one magnet must be placed with the north side facing the plate and the other with the south side. In this way, the magnets can be stylized and achieve a decrease in the strength of the magnetic field.

Another way to distribute the magnets so that they are not affected is: in the form of a circle so that the number of poles with a different directionalso achieves a neutralization of the field.

2. Distance required

As the distance between one magnet and another increase, the field strength decreases. We must also take into account the distance of the magnet from the envelope because if the envelope is very thin and the distance to the outside is small, this could affect the surrounding magnetic elements. This is why we can fill the space with materials that allow the isolation of the magnets, such as plastic.

In addition to these two factors mentioned above, we can also place an iron plate on each pole to protect the intensity of the field. Even so, before sending the package we must measure the magnetic force, by means of a Gaussmeter or Teslameter.
