SUMMARY

This discussion centers on the feasibility of inducing an electric current through heating, specifically using metal rods. The concept of a thermocouple is highlighted as a practical example, where temperature differences create a voltage that can drive current. The conversation confirms that while heating can induce a current, the direction and magnitude depend on the materials used and the temperature gradient established. The use of conducting and non-conducting rods is also explored, emphasizing the role of material properties in current generation.

PREREQUISITES
  • Understanding of thermoelectric effects, particularly Seebeck effect
  • Familiarity with thermocouples and their applications
  • Knowledge of electrical conductivity in various materials
  • Basic principles of heat transfer and temperature gradients
NEXT STEPS
  • Research the Seebeck coefficient of different materials
  • Explore the design and application of thermocouples in temperature measurement
  • Investigate the relationship between temperature gradients and induced voltage
  • Learn about the principles of thermoelectric generators and their efficiency
USEFUL FOR

Electrical engineers, physicists, and anyone interested in thermoelectric applications and current generation through thermal processes.

Is it possible to induce a current with just heating?
i.e. if we have metal rods (conducting/non-conducting rods) and a heat source, can we make current and determine the direction and amount of current (if possible in relation to the heat energy)?

Thread 'Colors in a plasma globe'
I have a common plasma globe with blue streamers and orange pads at both ends. The orange light is emitted by neon and the blue light is presumably emitted by argon and xenon. Why are the streamers blue while the pads at both ends are orange? A plasma globe's electric field is strong near the central electrode, decreasing with distance, so I would not expect the orange color at both ends.
