Has anyone seen magnetic or electric flux?
Answer:
Well yeah. Light is a fluxuating electro-magnetic field. But magnetic fields, and electric fields, by themselves, are invisible.
It cannot be seen, just like the flow of electrons in a wire. You can feel it, but you can't see it.
you can not see these two but can only see their manifestations i.e iron filings on top of a paper will move if there is a magnet underneath being moved
Flux cannot be seen. It is invisible to our eyes.
The EFFECTS can be seen by way of effected metals, ie: metal filings.
Use a common magnet... place a piece of paper on top of it and then gently pour iron filings on the paper. The flux lines will show up after being aligned by the magnet.
Nobody can see a magnetic flux it is imaginary.
Magnetic and electric flux are abstractions.
Electric flux tells one the force and the direction of the force that would exist on a point charge if it were located at a given point in a electric field.
Magnetic flux tells one the direction of a field (how a small magnetic dipole would line up) and the intensity of the magnetic field at any given point in space.
It is convenient to use flux lines to diagram the direction of a field and the space between the lines is an indication of the strength of the field but these lines are just an abstraction and they can be somewhat misleading to students who may ask why is that line here and not a mm over in that direction. The exact placement of any given flux line has no more significance than a line of equal elevation on a topographical map. There is an arbitrariness in the lines selected.
Also, people say that iron fileings line up with magnetic flux lines. This is true in a sense; however, if the filings are removed and sprinkled down in the field a second time the lines locations may be shifted. What is significant is the direction of the lines at any given point and the distance between them. The exact location of any line (of filings) is by chance only.
put a piece of paper over a magnet and sprinkle iron filings over it then you will see magnetic flux
