kinki bracelet

This project by Marta Lwin delves into the principles of electromagnetism, particularly focusing on generating electric current through the movement of conductors like copper wire in magnetic fields. The experiments conducted involve various coil and magnet configurations, emphasizing the crucial ratio of coil diameter to magnet size. Preliminary results highlight the need for wider coil radius for effective functionality. Future steps include testing stronger magnets and redesigning the holding container to enhance performance. Join us as we explore the innovative developments in electromagnet technology.

  1. kinki bracelet microtech project by marta lwin

  2. Faraday principal of electromagnetism

  3. If an electric conductor, like copper wire, is moved through a magnetic field, electric current will be generated and flow into the conductor.

  4. Electromagnet development Coil and magnet configuration experiments and results: .04 v .01 v

  5. .06 v .18 v

  6. Building the circuit

  7. .23 v before cap CAPACITOR .33 uf .50 uf 1 f LED .24 v .24 v .28 v at LED with a 1 f CAP at wires at end of bridge

  8. Things learned: The ratio of coil diameter to magnet is very important. In order to get this bracelet to work, it will require a much wider radius then, the coils I have tested.

  9. Further development steps: Test output of electromagnetic generator with a stronger magnet with greater diameter. Test coil configuration and it’s ratio to distance the magnet passes. Redesign shape of holding container to house the magnet and coil.
