Abstract
Matching components of a magnetic locking assembly are magnetically attracted into mating relationship until a predetermined magnetic flux is established in one of the components. Such established predetermined flux is monitored to detect locking power diminutions between the locking assembly components. External magnetic fields applied to the locking assembly in an attempt to counterfeit the mentioned predetermined magnetic flux may be detected and indicated for security reasons.

In a method of operating a magnetic locking assembly having matching first and second magnetizable components, the improvement comprising in combination the steps of:
- magnetically attracting said first and second components into mating relationship whereby a predetermined magnetic flux is established in one of said components;
- and
- monitoring said established predetermined flux to detect locking power diminutions between said components.
In a method of operating a magnetic locking assembly having matching first and second magnetizable components, the improvement comprising in combination the steps of:
- providing a pair of magnetic pole faces in one of said components;
- magnetically attracting said first and second components into mating relationship whereby a predetermined magnetic flux is established between said pole faces;
- and
- monitoring said established predetermined flux between said pole faces to detect locking power diminutions between said components.
In apparatus for operating a magnetic locking assembly having matching first and second magnetizable components, the improvement comprising in combination:
- means for magnetically attracting said first and second components into mating relationship whereby a predetermined magnetic flux is established in one of said components;
- and
- means coupled to said attracting means for monitoring said established predetermined flux to detect locking power diminutions between said components.
