Hand Generator Hand Alternator Experimental Apparatus for Physics Education
.Two kinds of motors can be demonstrated: demonstration alternator, first move the brush to the whole ring part of the collecting ring, then use sliding varistor, DC current meter to form the external circuit, connect the output end of the generator to slowly rotate the generator rotor, galvanometer will clearly show the direction of current change, or you can use DC voltmeter to connect to the output for demonstration
.Demonstrate the DC generator: Move the brush to the commutator section, the external circuit does not rotate the rotor, and the galvanometer pointer deflects in one direction, indicating that the output is DC
.Design Science: The base of the machine is wooden, the plane is not deformed, no cracks, four feet to flat, no shaking, the paint surface should be smooth and beautiful .The fasteners on the bottom plate shall not be loose, and the rotating parts shall be flexible and uniform, with low noise
.High Playability: Exquisite details, can be a high-grade home and office decoration. The product is suitable for people over 6 years old and is a great gift for people who is inteterested in science and physics.
