Within a material, what results in the conversion of an electron's energy to thermal energy and electromagnetical energy?
The electron moving makes an magnetic field, if it changes, there will be an electric field with the magnetic field.
Thermal energy is the result of collisions of the electron with other things.
Within a material, the conversion of an electron's energy to thermal energy and electromagnetic energy is caused by two main processes: electron collisions and electron motion.
1. Electron Collisions: When an electron collides with other atoms or molecules in the material, it transfers some of its energy to those particles. This transfer of energy leads to the generation of thermal energy, which increases the overall temperature of the material. The more collisions the electron experiences, the greater the conversion of its energy into thermal energy.
2. Electron Motion: Moving electrons create a magnetic field around them. If the electron's motion changes, this magnetic field also changes, thereby inducing an electric field along with it. This phenomenon is known as electromagnetic radiation or electromagnetic energy. When electrons accelerate or decelerate due to external forces or interactions, they emit electromagnetic waves (such as light or radio waves) as a result of this changing electric and magnetic field.
In summary, the conversion of an electron's energy to thermal energy occurs through collisions with other particles in the material. On the other hand, the conversion of electron energy to electromagnetic energy occurs when the electrons' motion changes, thereby creating changing electric and magnetic fields that give rise to electromagnetic radiation.
