2 Problem #1 A magnetic field B, directed toward the negative z direction, fills the space with x>0 . The magnitude of the magnetic field changes with distance x’ from the y -axis according to the expression: ' Cx B = , where C is a constant. A square loop of wire with resistance R and side L is placed with the left side at a distance x from the y -axis (see figure). a) Calculate the flux of the magnetic field through the grey area inside the loop which is at a distance x’ from the y -axis and has width dx’ . b) Find the total flux Φ B of the magnetic field through the loop, as a function of x, for x>0 . c)
