Let's consider a loop of wire with an unknown shape but in order to analyze it we need to assume a specific shape. A rectangular shape seems to be appropriate and obviously has a length L, a width w and lies in the x-y plane with the magnetic field oriented along the +z direction. Give the expression of: a) The magnetic flux density through the loop b) The emf induced in the loop with N turns at time t c) The instantaneous emf d) How does the overtime variation of the magnetic field affect the magnetic flux and the current? B = 3e -t/3,

Let's consider a loop of wire with an unknown shape but in order to analyze it we need to
assume a specific shape. A rectangular shape seems to be appropriate and obviously has a length
L, a width w and lies in the x-y plane with the magnetic field oriented along the +z direction.
Give the expression of:
a) The magnetic flux density through the loop
b) The emf induced in the loop with N turns at time t
c) The instantaneous emf
d) How does the overtime variation of the magnetic field affect the magnetic flux and the
current?
