Q4/ A cylindrical coil of length L
20 cm, its area is A1 = 40 cm^2
and the number of its turns is
%3D
20000 = N1. Inside it and in the
%3D
middle is a short coil so that the
two coils have a common axis. If
you know that the length of the
short coil is 20cm = L2, its area
is A2=40cm^2 and the number of
its turns is 200=N2, find: 1- The
%3D
mutual inductance coefficient
between the two coils. 2- KDC
induced in the short coil if the
current in the long coil changes
according to the equation
0.25cos377t^2=I when t=1/120
