Will the ferromagnetic impurities filtered out by the strong magnetic oil filter harm the engine twice?

The new product Daji brand strong magnetic oil filter, is the use of permanent neodymium iron boron magnets made of strong magnetic filter element, it is not because of the use of time and use of the environment and demagnetization. Science has proved that there are only two ways to demagnetize permanent magnets:

One is to demagnetize them by using equipment with an alternating electric field. This does not occur during the use of a strong magnetic oil filter;

The other is the loss or disappearance of the magnetic field when the ambient temperature where the strong magnet steel is located is higher than its design temperature resistance parameter. As we use the magnetic cartridge, is made of N30SH above grade high-temperature NdFeB magnet steel, its theoretical temperature resistance of 150 ℃ will not be demagnetized, the actual by us using 135 ℃ long-term test and not demagnetized, and the normal operating temperature of the engine between 85 ℃ -95 ℃, even in the special state of the limiting temperature is not more than 115 ℃.

Because of the above demagnetization conditions, so the new product Daji brand strong magnetic oil filter element will not be used due to high ambient temperatures or other factors affect the demagnetization, and will not bring secondary wear to the engine.
