ABSTRACT:
A method of measuring the retention force of a biomedical specimen coupled to a carrier includes the measurement of the force required for magnetically decoupling the specimen from the carrier. In one embodiment, the method includes the steps of providing the specimen with an electrically conductive structure; creating an external alternating magnetic field near the specimen; increasing the amplitude and/or frequency of the magnetic field; detecting the start of the movement of the specimen on the carrier; and calculating the retention force of the specimen by determining the applied magnetic force on the basis of the parameters of the magnetic field. In other embodiments, the magnetic field may remain constant and the biomedical specimen may be moved through the field at varying speeds.
