Abstract

Przedmiotem zgłoszenia jest wózek do badania siły elektrodynamicznej, mający zastosowanie w pracowniach fizycznych, szczególnie do celów edukacyjnych. Wózek do badania siły elektrodynamicznej zawiera poziomą, prostokątną płytę nośną (1), zaopatrzoną w trzy rozmieszczone symetrycznie prostokątne otwory, przy czym w tylnej części płyty nośnej (1) znajdują się dwa otwory, a w jej przedniej części jeden otwór. Od dołu do płyty nośnej (1), w pobliżu podłużnych krawędzi każdego z prostokątnych otworów, przymocowane są łożyska ślizgowe (2), przez które przechodzą osie (3), zaopatrzone w koła (4, 5). Do obwodu koła napędowego (5) dotyka szczotka (6), a do płyty nośnej (1) od góry zamocowany został również magnes trwały, złożony z dwóch prostopadłościennych sztabek magnetycznych (7, 8), ustawionych równolegle do płaszczyzny koła napędowego (5), zaś końce sztabek zostały połączone ferromagnetyczną zworą (9). Na płycie nośnej (1) znajduje się też pojemnik (10) z akumulatorem (11), połączonym z przełącznikiem kierunku przepływu prądu, mającym suwak (12) z dwiema parami odizolowanych od siebie styków. Ponadto jeden z przewodów (13), wychodzących z przełącznika kierunku przepływu prądu jest doprowadzony do szczotki (6), a drugi z tych przewodów (14) przyłączony do łożyska koła napędowego (5).The subject of the application is a trolley for testing electrodynamic force, applicable in physical laboratories, especially for educational purposes. The trolley for testing the electrodynamic force contains a horizontal, rectangular support plate (1), provided with three symmetrically arranged rectangular holes, with two holes in the back of the support plate (1) and one hole in its front. From below to the support plate (1), near the longitudinal edges of each of the rectangular holes, plain bearings (2) are mounted, through which the axles (3), fitted with wheels (4, 5), pass. A brush (6) touches the periphery of the drive wheel (5), and a permanent magnet, consisting of two rectangular magnetic bars (7, 8), parallel to the plane of the drive wheel (5) is attached to the support plate (1) from above. while the ends of the bars were connected by a ferromagnetic armature (9). On the support plate (1) there is also a container (10) with a battery (11), connected to a current direction switch, having a slider (12) with two pairs of insulated contacts. In addition, one of the wires (13) coming out of the current direction switch is fed to the brush (6), and the other of these wires (14) connected to the drive wheel bearing (5).
