Electric
Generators
Electric generators usually
consist of a set of coils (rotor) spinning between two strong magnets (stator).
In general any moving magnetic force induces some electricity in the wires
(conductors) that are close to it. The main challenges in designing an electric
generator are identifying ways to optimize the production of electricity. Some
of the ways you can increase the efficiency of an electric generator are using a
very strong magnet and keeping the magnet very close to the coil. Here are some
of the electric generators available at MiniScience.

Bicycle Generator,
6-Volts
This is a small electric generator that may be attached to a bike or any
turning tire to produce electricity. The amount of electricity depends
on the speed of turning. It is rated as 6 Volt and 3 Watts.
When attached to a working model of windmill or water mill it can
produce electricity to lit a few light a few miniature light bulbs. It
must spin at a rate of 600 rpm or more to produce electricity. |
Product Code: BGEN6V3W |
Bicycle Generator,
12-Volts
This is a small electric generator that may be attached to a bike or any
turning tire to produce electricity. The amount of electricity depends
on the speed of turning. It is rated as 12 Volt and 6 Watts.
When attached to a working model of windmill or water mill it can
produce electricity to lit a few light a few miniature light bulbs. It
must spin at a rate of 600 rpm or more to produce electricity.

Product Code: BGEN12V6W |
Wooden Generator,
Science Kit
This is a DIY electrical generator for students who want to make their
own electrical generator. In this model to rotor is a strong magnet
(inside the box) that turns inside a conductive coil.
Fast turning of the wood dowel will lit the lights.
