A 2.5-m-long, 2.0-mm-diameter aluminum wire has a potential difference of 1.5 V between its ends. Consider an electron halfway between the center of the wire and the surface that is moving parallel to the wire at the drift speed. What is the ratio of the electric force on the electron to the magnetic force on the electron?
Frontiers in Astronomy Week 3 Radiation- Ch. 3 Information from the skies light was the only connection to space today, light is nothing else but a form of radiation, electromagnetic waves besides probe exploration (limited to our solar system), light and electromagnetic radiation is still the main connection to cosmos other connections are the cosmic rays, neutrino and gravitational waves but the main connection is electromagnetic radiation Electromagnetic radiation transmission of electromagnetic energy through space without physical connection through varying electric and magnetic fields Ex. Light, radio signals Waves moving disturbance
