Product Description

This model uses the same basic assembly as the motor, but is mounted on a baseplate 230 x 90 mm. approx. which also carries a hand-drive pulley 120mm. diameter coupled to the smaller dynamo pulley by a rubber belt to give a step-up ration. Electrical output is via a pair of 4mm. sockets. The model may also be used as a motor on a 6-8 V D.C. supply.

This demonstration dynamo offers a hands-on experience for students learning about energy conversion. Its transparent housing allows direct observation of the coil and magnet interaction, providing clear evidence of Faraday's Law in a safe classroom environment. Watch as mechanical rotation is transformed into electrical current through simple manual cranking.


Safe, Durable, and Classroom-Ready

Made from robust stainless steel and transparent plastic, the device features enclosed moving parts for safety and stability via rubber feet. The design is optimized for repeated educational use, letting students explore its principles without risk of injury, while its compact size fits easily on any lab bench.

FAQ's of Demonstration Dynamo:


Q: How does the demonstration dynamo illustrate energy conversion?

A: The dynamo converts mechanical energy from hand cranking into electrical energy via electromagnetic induction. As users rotate the armature, the relative motion between the coil and the magnet inside the transparent enclosure generates an electrical current, providing a direct demonstration of Faraday's Law.

Q: What is the recommended usage for this apparatus?

A: This device is intended for classroom and laboratory demonstrations of electromagnetic induction. It can be connected to meters, bulbs, or other devices using its 4mm output terminals, allowing students to observe current and voltage changes by altering the crank speed.

Q: When should I use the demonstration dynamo in a lesson?

A: Use the dynamo during lessons involving electricity, magnetism, or energy transformation. It serves as a practical illustration when explaining theoretical concepts like Faraday's Law or the principles behind electric generators.

Q: Where should the demonstration dynamo be placed for safe operation?

A: Place the device on a stable, flat surface such as a laboratory or classroom desk. Its rubber feet provide grip to prevent movement during use, ensuring optimal safety and performance.

Q: What is the process for operating the dynamo?

A: To operate, connect suitable output devices to the terminals, then rotate the manual crank. The speed of rotation directly affects the amount of electrical current and voltage produced. Observe the generator's internal mechanism through its transparent housing to reinforce learning.

Q: What educational benefits does this equipment provide?

A: The dynamo offers visual, tactile, and interactive learning, helping students grasp abstract concepts in physics through hands-on experience. It deepens understanding of electromagnetic induction by making the conversion of energy both observable and measurable.
