Magnectic field and electrical interaction

AI Thread Summary
A beginner in physics seeks clarification on how magnetic fields affect moving electrical charges, noting that Wikipedia mentions detection through effects on charges but lacks detail on the interaction. The discussion highlights that the force exerted by a magnetic field on a moving charge is perpendicular to both the charge's velocity and the magnetic field direction. A link to HyperPhysics is shared for further reading, although some find the material complex. A visual representation of an electron beam in a magnetic field is mentioned as helpful for understanding the concept. The conversation emphasizes the importance of visual aids in grasping complex physics topics.

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.

interesting Bob, and true the image does help explain visually what I am trying to read in the above site, thanks very much
 
Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'
So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
