Magnets are no toys
Magnets are not toys! Due to the force here can quickly arise bruises. Also small parts can be swallowed by children.
Splitter - danger
Magnets can shatter on impact, with flying debris can injure eyes locally! Apply for this reason, when dealing with magnets goggles and avoid unnecessary collisions.
Danger to life
Magnets can affect the operation of cardiac pacemakers and defibrillators, so any progress is strictly prohibited here!
Effect on objects
Magnetic fields can damage electrical and mechanical devices such as laptops, watches, debit cards, disks, speakers, or the key to their cars. Make sure that such items do not get in the near magnets.
Risk of injury
Some magnets have such a strong attraction forces (up to several 100 kg) that caution should be exercised. Always make sure that no parts of the body between two magnets lie, otherwise can bruises or even fractures occur. Apply for this reason, always wear protective gloves.
Allergies
Almost all magnets have nickel - coatings. For some people, this can lead to allergic reactions, which is why these on the contact with magnets which a nickel - should have coating without.
Shipping of magnets
The mail delivery is the most suitable variant to transport magnets from A to B, but caution is required here, because not in accordance packaged magnets can damage sensitive equipment in other packages or sorting devices.
Health effects
According to present knowledge could no harmful effect on humans, caused by magnets, are proved. However, it is recommended to have no lasting contact with magnetic fields.
Temperature-related effects
Magnets are up to a temperature of 80 ° C fully used (a few even up to 200 ° C). Above this temperature they lose continuously, the higher the temperature is, permanently in power.
Oxidation - corrosion - rust and related effects
To protect against above-mentioned external influences, most magnets have a thin nickel - copper - nickel - coating, however, which is fragile and not weather-resistant enough for sustained outdoor use.
Splinter effects
Above-mentioned coating can already split up by the smallest mechanical stress or pressure, because it is very brittle. This magnet is then open and is more sensitive to external influences.
Processing-related effects
Magnets are not suitable for mechanical processing by laymen, as when sawing or drilling can break the magnets and this heat can lead to demagnetization. Also at this point, the coating would be missing. However, experts can perform with diamond tool and a special form of cooling with plenty of time such operations.
