METHOD FOR DEMONSTRATION OF RIGHT-HAND AMPERE'S RULE IN PHYSICS LESSONS AND DEVICE FOR ITS IMPLEMENTATION (EMBODIMENTS)

摘要

FIELD: physics.SUBSTANCE: inventions relate to the field of formation and can be used to increase presentation of educational material when studying the most important for engineering sections of physics - mechanics, electromagnetism and optics. Demonstration of the rule is carried out by turning a screw with a right-hand thread and caused by this rotation of translational motion of the screw along its axis, translational movement of the screw with a right-hand thread is performed relative to the plate, which is located perpendicular to the axis of the screw with a right-hand thread and has a plan view of a shape of two arrows arranged at an angle to each other and denoting directions of vectors, wherein direction of vector product vectors are determined in direction of translational movement of propeller during rotation of screw at smaller angle between arrows, axes of which intersect on axis of rotation of propeller. First version of the device is characterized by that the right-hand screw is a corkscrew with a handle perpendicular to the corkscrew axis, the corkscrew is screwed into the plug from the wine bottle, on the end surface of which there is a plate perpendicular to the rotational axis of the corkscrew, which has a plan in the form of two arrows arranged at an angle to each other, wherein the shooter axes intersect on the rotation axis of the corkscrew. Device according to second version comprises base made in form of flat plate, in central part of which there is a coupling, made with central right-hand thread, in coupling perpendicular to base right-hand thread screw is installed, on the surface of the flat plate on the side opposite to the side with which the screw is installed in the coupling, the second plate parallel to the base is located, which has a plan of the shape of two pointers located at an angle to each other, at that the shooter axes intersect on the rotor axis of the screw.EFFECT: technical result is faster study and higher quality of assimilation of right-hand Ampere's rule in physics lessons.5 cl, 8 dwg
