The discussion centers on the interaction between magnetic fields and electrons, clarifying that magnetic fields neither attract nor repel electrons directly. Instead, they exert a force on electrons that is perpendicular to both the magnetic field and the electron's velocity, described by the Lorentz force. The phenomenon of feeling pressure when two like-polarity magnets are brought together is identified as magnetic repulsion. Additionally, it is confirmed that charged particles, including protons and electrons, can pass through magnetic fields, with changing magnetic fields being a method to steer electron beams.
PREREQUISITESPhysics students, electrical engineers, and anyone interested in the principles of electromagnetism and particle physics.
Neither. You get a force in the direction perpendicular to both the field and the velocity of the electron. Look up the Lorentz force if you are familiar with cross products of vectors, or Fleming's Left Hand Rule if you aren't.gmoney909 said:does a magnetic field repel or attract electrons ?
Magnetic repulsion, usually.gmoney909 said:Also when you place two magnets together with the same polarity and you feel that pressure - what is this called
Sure. Changing magnetic fields is one way to steer an electron (or any other kind of charged particle) beam.gmoney909 said:can protons or electrons pass through this field
