by a reversed method i go: 1. I=e/R -> 0.35=e/10 -------hence e=3.5 V since directly prop then it becomes 3.5 Wb 2. magnetic flux= B.dS ------ 3.5= B.dS where S (surface area) = 0.1x0.1 = 0.01m^2 it comes out B= 3.5/0.01 = 350 T But how do i do it the right way around rather then back wards...

magnetic flux = B.dS where S is the surface area (0.01m^2). emf is directly proportional to the rate of change of magnetic flux, so e= d(magnetic flux) / dt -> those that mean that 150T/s = e ? (1 T= 1Wb.m^-2) if so then 150=Bx0.01 which makes B=15000 T But that can't be right. I am not sure...

thanks again!

still stuck

thanks, ill take a look around the notes again
