Abstract
A device is disclosed herein for measuring the pressure that a magnetic object exerts which includes a housing having a movable diaphragm held in a taut condition across an internal cavity. A central area of the diaphragm mounts a metallic or magnetic sensitive element operable in response to the presence of a magnetic field to move into and out of the internal cavity to create a detectable and readable pressure level. An analog or digital meter displays the pressure reading. The problem of determining the force exerted by a magnetic field is solved directly.
