FIELD: physics.
SUBSTANCE: field is created by a magnetic explosion generator based on one circular winding of an exploding wire, through whose centre the ferromagnetic metal fibre is passed, said fibre being stretched by a force close to a breaking force in the absence of a magnetic field. The plane of the winding is strictly orthogonal to the stretched fibre which is protected from the exploding winding by a piece of glass tube. The ends of the stretched ferromagnetic metal fibre are electrically connected to a measuring device, for example, a resonance amplifier or an oscilloscope, which picks up damped electric oscillations arising when the fibre breaks.
EFFECT: recording EMF which arises upon breakage of a ferromagnetic metal fibre which is stretched by a defined force, taking place under the action a localised superstrong magnetic field.
