How does a magnetic field affect an electrical field

AI Thread Summary
A magnetic field influences an electrical field through the interaction of charged particles, but the effect on a nonferrous charged object is minimal. When a magnet is brought near such an object, it does not significantly alter the object's charge or behavior. The discussion raises curiosity about the measurements taken during MRI scans, which utilize magnetic fields to visualize internal structures. MRI technology relies on the magnetic properties of hydrogen atoms in the body, rather than direct interactions with charged objects. Understanding these principles is essential for grasping how MRI imaging works.

More specifically, what happens and why when a magnet is brought close to a nonferrous charged object.
 
Physics news on Phys.org
Nothing much.
 
This me wonder about what it is that is being measured with an MRI scan though.
 
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...
