SUMMARY

This discussion centers on the application of Faraday's Law of Magnetic Induction in the design of a shoe that generates power while running. The user, Chad, seeks to estimate the wattage produced by a smaller magnet to potentially eliminate the need for a battery or capacitor in the shoe, enabling direct charging of devices like phones or iPods. The response emphasizes the importance of consulting technical staff or hiring an engineer for accurate calculations, particularly for commercial applications.

PREREQUISITES
  • Understanding of Faraday's Law of Magnetic Induction
  • Basic principles of electrical engineering
  • Knowledge of capacitor functionality and energy storage
  • Familiarity with power calculations (wattage and voltage)
NEXT STEPS
  • Research practical applications of Faraday's Law in wearable technology
  • Explore methods for calculating power output from magnets
  • Investigate energy harvesting techniques for portable devices
  • Learn about capacitor sizing and selection for energy storage
USEFUL FOR

Industrial designers, electrical engineers, and anyone interested in integrating energy harvesting technologies into wearable devices.

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.
