What is the Definition of Change in Magnetic Flux?

Click For Summary
SUMMARY

The discussion clarifies that "change in magnetic flux" refers to the variation of magnetic flux through a defined surface area over time. A key example provided is a rotating coil within a constant magnetic field (B-field), where the magnetic flux changes due to the continuous alteration of the area exposed to the magnetic field. Magnetic flux is defined as the product of magnetic field strength and area, expressed mathematically as magnetic flux = magnetic field strength x area. Therefore, the change in magnetic flux is directly related to how the magnetic field strength varies across that area.

Hi all,

Could anyone pls explain me in detail (preferably with an example) what "change in magnetic flux" is...Thank you

Well the change in magnetic is um, just what it says, simply the change in flux through some defined surface. For example, when we have a rotating coil in a constant B-field, the magnetic flux through the loop continually changes because the area of the loop through which the B-field passes changes all the time. What do you understand by magnetic flux?
 
Well my understanding of magnetic flux is that its the product of the magnetic flield strenght and the area.. so

magnetic flux = magnetic field strength x area

so change of magnetic flux is how the magnetic field strength changes changes over an area?

dunno if that's much help (someone might have to check if I am right bout the second bit =] )
