What should I do if the lifting electromagnet is not demagnetized and still attracts objects after turning off the power? Although this problem is unlikely to occur, special circumstances are not excluded. What should we do if the lifting electromagnet is not demagnetized?

During the operation, the residual magnetization operation should be performed on the object first. This method is to pass a reverse current in the chuck coil and control the size and time of the current to achieve the purpose of degaussing. It is worth noting that the current should not be too large during degaussing. Pay attention to current size and time control to avoid diamagnetic phenomena.
When using the lifting electromagnet, you should pay attention to correct operation and demagnetize it from time to time after using it for a period of time to avoid the phenomenon that the lifting electromagnet does not demagnetize.
During operation, please pay attention to the activities of nearby people to prevent the electromagnet from falling during operation.
In order to prevent the lifting electromagnet hook from wandering, the driver must comply with the operating regulations and place it correctly during lifting operations;
When starting a car, start slowly step by step and adjust the brakes of large and small cars appropriately; try to start and stop smoothly;
When lifting light objects, do not choose a shorter rope buckle. Please take the above measures to prevent electromagnetic hooks and objects from lifting.
Eliminate hook swing: Stable hook: When swing occurs due to improper operation of the lifting electromagnet, the "following car" method should be used to eliminate the swing.
For example, when the hook swings in different directions, when the swing has not yet reached a large value, the body suddenly pushes the hook in the same direction;
Stop exploring and stay ahead of the curve. At this time, the speed of the vehicle body is close to or equal to the horizontal direction of the hook, and the relative speed between the two is almost equal to zero, and the hook can be stable. Lift the distance between the position of the lifting electromagnet slide rod and the position of the fully adsorbed state. The lifting electromagnet will produce different forces in different strokes; generally, the smaller the operation, the greater the force.
