Can you really create an electrical current with magnetics and copper coil?

When it comes to cheap the students are not as confident in the math and leary about Chinese datasheet.
A descent current producing generator has a level of authenticity that makes a hands on demo an unforgettable experience.
Because the parts inside a good generator have always had significant cost. It should have a data sheet and the teaching skill being most important,
To support the falling magnets and the forces of eddy currents a real generator could be used when enough background is covered.
For $29.00 We find the over rating on the Chinese data sheet is very disappointing but you can pay shipping and send it back lose a few months waiting. This means the electric bike is'nt going to get charged very good with this, back to the drawing board.
You can crank this until the cows come in and not charge a car battery. When you use 2.5 HP and 90 AMP alternator for 10 minets
the car battery will store adequate power for camping. The solar panel is more cost effective but is much slower.

The relative cost for minimal power such as camping is a conservative approximation that helps young people see what is involved.
The Chinese selling these are laughing that the American little goody two shoes will never charge a Walmart electric bike.
