AC/DC Hand Driven Dynamo Generator for School Physics Experiments and Demonstrations

Product details

F - Feature (Characteristic) Dual-mode output: It can be switched by the commutator to simultaneously demonstrate both AC and DC power generation. Core structure: Composed of a hand-cranked large wheel, transmission belt, copper coil winding, N/S pole permanent magnets, commutator, terminals and indicator lights. The base is made of wood. Clear principle: Based on Faraday's law of electromagnetic induction, the coil cuts the magnetic field lines to generate induced current.

A - Advantage (Benefit) Multi-purpose: One device can complete the teaching of both AC and DC power generation principles, without the need to purchase two sets of teaching aids separately. Intuitive comparison: By switching the switch, the waveforms and output differences between AC and DC electricity can be clearly compared, reducing the difficulty of teaching. Easy operation: Hand-cranked drive, no need for an external power source, modular structure, facilitating disassembly and explanation of the internal structure.

B - Benefit (Advantage) Improvement in teaching efficiency: Helps students understand the essence of both currents in the same experiment, deepens the mastery of electromagnetic knowledge, and enhances classroom interactivity. Cost optimization: Reduces the number of teaching aids purchased and storage space, lowers the long-term investment cost for educational institutions. Widely applicable: Suitable for physics classes in primary and secondary schools, university engineering experiments and science and technology museum popularization, meeting different levels of teaching and display needs.
