Magnectic field and electrical interaction

Click For Summary

Discussion Overview

The discussion centers around the relationship between magnetic fields and electrical charges, particularly how magnetic fields affect moving electrical charges and currents. Participants explore the effects of magnetic fields on electrical currents and seek further understanding of the underlying principles.

Discussion Character

  • Exploratory, Conceptual clarification, Technical explanation

Main Points Raised

  • A beginner in physics questions how electrical charges are affected by magnetic fields, specifically whether the current is weakened or distorted.
  • One participant provides a link to an external resource that discusses magnetic forces on electric charges.
  • A later reply expresses gratitude for the resource, noting that while some content is complex, it ultimately answered the initial question.
  • Another participant shares a visual example involving a vacuum tube and a Helmholtz coil, illustrating the deflection of an electron beam in a magnetic field, emphasizing the perpendicular relationship between beam velocity and magnetic field direction.
  • A subsequent reply acknowledges the helpfulness of the visual explanation in understanding the concepts discussed.

Areas of Agreement / Disagreement

The discussion remains unresolved regarding the specific effects of magnetic fields on electrical currents, with no consensus reached on the nuances of the relationship.

Contextual Notes

Participants express varying levels of understanding, with some content being perceived as complex and potentially requiring additional foundational knowledge.

Who May Find This Useful

simple question from a beginner to physics, in wikipedia it states that a magnetic field can be detected by its affects on a moving electrical charge, but does "not" go onto say how an electrical charge is affected by magnetic fields, is the current weakened/distorted or am i swinging in the dark here, my question is could someone give a detailed explanation as to the relationship between electrical current and magnetic fields, or could someone provide a link to some reading material on this subject.

"Quote From Wikipedia" and is detected by the force it exerts on other magnetic materials and moving electric charges

thanks very much, a lot of that article is far above my current knowledge on the subject but its very interesting reading, the equations are very complex to my eyes but it did answer my question :)
thanks
 
A picture is worth 1000 words and 100 formulas. See the thumbnail of a ~300 volt electron beam in a vacuum tube inside a Helmholz coil. The deflection force is perpendicular to BOTH the beam velocity AND the direction of the magnetic field. Residual gas in the vacuum tube is excited by the beam as it passes.
