What is the reason for the poor anti-interference effect or inability of the magnetic ring to resist interference?

    Many people are not sure why a magnetic ring is added to the product, but it cannot achieve anti-interference effect?
In fact, the product is equipped with a magnetic ring, which cannot provide anti-interference effect. There are several reasons, as follows:
    1： After adding a magnetic ring, check if the product has not responded at all. If so, then the frequency of the magnetic ring is incorrect. We need to choose a suitable magnetic ring based on the frequency of product interference in order to eliminate the interference one by one.
    2： If we are not clear about the frequency of product interference, we will spend more time and conduct testing; For example, choose low-frequency magnetic rings for testing. If not, then choose high-frequency magnetic rings or high-power magnetic rings, and try to test as much as possible. I believe there will always be a magnetic ring suitable for your electronic product.
    3： During the experiment, if the low-frequency magnetic ring did not reflect, but the high-frequency magnetic ring did, but the interference problem could not be solved. This is because the interference signal is too strong, and one magnetic ring cannot withstand the attack of interference. It is necessary to add one or two more magnetic rings until the electronic product can operate normally.
    4： Many products have added magnetic rings that are still good the first day, but by the morning of the second day, they are no longer good. This indicates that the magnetic ring has become saturated, and it is necessary to add one or two more magnetic rings.      If it still does not work, then it is necessary to start with the material of the magnetic ring and try to choose magnetic rings made of materials with high characteristics. Additionally, it is recommended to wind more circles on the interference source line as much as possible, and also add magnetic rings at the inlet and outlet ends of the interference source line, You can eliminate all the interference signals in one go.
