See attached MDFA PullTest Standard. When lifting an object with amagnet, many factors can affect the ability of the magnet to lift a givenweight. These factors include: surface finish of magnet & object, flatnessof magnet & object, coating on either surface & acceleration of liftingmotion. Consult our Technical Department for more information on liftingmagnets.
