How can a strong magnet steal electricity?
A powerful magnet is a neodymium iron boron magnet. Its magnetic properties greatly exceed the magnets such as ferrite magnets, aluminum-nickel-cobalt, samarium-cobalt, etc. The neodymium-iron-boron magnets are so strong that they can absorb objects 640 times heavier, and the rivers and lakes call them “strong magnets”.
Because the meter, the water meter is a shovel, I have been listening to people all the time. The strong magnet on the meter can steal electricity, so many people want to know how to steal electricity.
The principle of stealing electricity, the magnetic force of the magnet is very strong, so that the pointer can not move, or the machine fails. Other methods of stealing electricity, using a 2.5 square wire on the meter to erect on the meter, do not need to buy electricity directly, directly used, but easily caught by the property.
So, is this powerful magnetic stealing method still practical?
Now the gear materials in the meter are all copper. The copper gear is wear-resistant. Another important reason is to prevent some people from illegally stealing electricity. Most of them are induction meters, and the magnets have no point. The meter is metered by the sampling resistor (several milliohms) connected in series in the circuit. The magnetic field has no influence on the metering accuracy, and has the function of preventing reverse tampering.
According to the staff of the Water Group, the movements and hands inside the water meter in the user’s home are made of plastic or stainless steel and will not react to the magnet. Therefore, it is no longer feasible to steal electricity through a strong magnet.
