mag. dipole moment

Asked by  | 11th Apr, 2008, 08:56: PM

Expert Answer:

magnetic dipole moment is given by= current in the  closed loop multiply by the area of the loop

now in order to find the area of the loop we need to find the radius of the loop so we go like this

circumference of the wire= length of the wire


so r=(l/2πr)

now magnetic dipole moment =  current(i) multiply by area of the  circular loop(πr2)

                                                       = iπ(l/2πr)2

                                                      = iπl2/4π2r2
