FIELD: measuring devices.
SUBSTANCE: method includes applying measured force to magnetic-resilient element, made of special magnetic material, perpendicularly to its axis along whole length0. Onto magnetic-resilient element alternating current or voltage are fed matching frequency of appearance of surface effect. Loading force is determined by measuring changes of surface resistance of magnetic-resilient element. Device for measuring force has body made in form of plat, on which magnetic-resilient element is fixed, made of special magnetic material, in form of electric conductor, placed in a spiral and connected to alternating current source, and also force application element. The latter is made in form a plate of electric-isolating material, placed in parallel to body plate and in contact along whole length to magnetic-resilient element, connected to alternating current or voltage source, providing for appearance of surface effect.
EFFECT: higher sensitivity.
