faradays law,,, wattage/voltage question?

hi, I am an industrial design major and am working on a project for a shoe. the shoe incorporates faraday's law of magnetic induction so that while you run, a magnet is going back and forth and powering a capacitor. my question is, how might i be able to come up with some rough/general numbers of how much power i could create with a smaller magnet, and would it be enough to take the battery/capacitor out of the shoe and plug into a phone or ipod to power it up? any info or websites i could visit would be greatly appreciated...
THANKS,
Chad

You should ask your technical staff or hire one if don't have one.
I do not feel making free engineering computations to be used in a commercial product.

Hello Chad,

That sounds like a very interesting project! To answer your question, we would need to know the specific details of your design, such as the size and strength of the magnet, the distance it moves, and the efficiency of the capacitor. These factors will greatly impact the amount of power generated.

In general, Faraday's law states that the induced voltage in a circuit is proportional to the rate of change of the magnetic field through the circuit. This means that the faster the magnet moves, the stronger the magnetic field and the greater the voltage induced. However, this also means that the size and strength of the magnet will play a significant role in the overall power output.

To get a rough estimate, you could use the equation P = VI, where P is power, V is voltage, and I is current. You would need to know the voltage output of your capacitor and the current it can supply to determine the power generated. However, keep in mind that this is just an estimate and the actual power output may vary depending on the design and efficiency of your system.

As for using the power to charge a phone or iPod, it is possible but it would depend on the power requirements of the device and the amount of power generated by your system. You may need to do some calculations and testing to determine if it is feasible.

I would suggest doing some research on similar projects and consulting with experts in the field of electromagnetism to get a better understanding of the potential power output of your design. Good luck with your project!
