ПРОВОДНИКИ В МАГНИТНОМ ПОЛЕ

This permanent magnet has an adjustable pole spacing and a high field strength arising from a use of two neodymium magnet elements. It comes with a black-finished iron yoke, knurled handles made of high-grade steel and attachable pole shoes ... еще

This equipment consists of a stable, firm, anodized-aluminum tripod with pre-defined magnet positions and accessory mountings. The deflection of the conductor swing can be adjusted in steps of 0, 15, 30 and 45 mm for current balance experiments ... еще

Comprising a motor armature without an iron core, this device is intended for installation inside the permanent magnet with adjustable pole spacing (P 1002660 ). The coil is rotated purely by the Lorentz force, its direction of rotation ... еще

Functioning model for demonstration of how a DC motor, as well as DC and AC generators, work. The model is equipped with a commutator, slip ring, pick-ups and armature coil and is mounted on a transparent acrylic plate with connection sockets ... еще

Equipment set for measuring force on a current-carrying conductor in a magnetic field as a function of the current, of the magnetic field or of the length of the conductor. The force is composed of the apparent change in the weight of the holder ... еще

The apparatus consists of a powerful U shaped magnet, a pair of brass rails complete with 4mm sockets and a brass axle. A power supply unit is connected to the rails. When the axle is placed on the rails the electric circuit is completed and ... еще
