Hello!
First of all excuse my English. I'm Swedish.
I'm doing an exprement in which I utilize the energy from the rotation in a stroller wheel to charge a 5V battery .
I plan to make a magnetic generator with a disc placed on a 10 " wheel, consisting of the 20 Neodymium magmeter on the radius of 52 mm from the wheel axis. 3 coils with iron core will be placed at a distance of 2 mm from the magnets . The stroller will roll at a speed of 5.3 km / h and I need to get about 8 V output from the generator.
I need help with setting up an equation to get the number of turns of the coil and also help with the choice of magnets. The magnets diameter should be about 10 mm.
Thanks in advance
Siri
