Are Sockets Magnetic

The socket is not magnetic. I have been asked countless times: Should sockets be magnetic? This is a crucial question for anyone concerned about electrical safety.

The Direct Conclusion

The direct conclusion: the shell of an industrial socket is usually not magnetic, the current-carrying parts inside it—that is, the contacts and terminals—must also be absolutely non-magnetic. High-quality industrial power solutions that meet CEE/IEC 60309 standards are all made of non-ferrous metals such as brass, copper or tin-phosphor bronze. Choose these materials for nothing else, is to see their top conductivity and corrosion resistance.

Be Careful

If you take a magnet and put it on the internal contact of an industrial plug or wall socket, if the magnet “snaps” and sucks it, then you have to be careful. This means that it is mixed with steel or iron. In our business, this material substitution is a joke about safety. The magnetic material has a much higher resistance than copper, which can lead to extremely rapid temperature rise under high load operation, voltage collapse, and even direct ignition or fire under heavy industrial load.

Analyze Specific Problems

Of course, we also have to analyze specific problems. Sometimes you may find that the mounting screws on the outside of the socket or the springs inside are a little magnetic. This is usually because they are made of steel, which does not keep me awake. But one thing is dead: as long as it is the core path of the current, it must be non-magnetic, so as to ensure that the current runs steadily and does not burn. If you find that the place where the current passes is magnetized during the inspection, don’t hesitate, that thing will have an accident sooner or later.
