    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 thats much help (someone might have to check if im right bout the second bit =] )
