a) In the middle of a coil, the magnetic field induction is B0 = 0.5 T. Determine the magnetic field induction B along the axis of the coil at its edge. b) In the middle of a capacitor, the electric field intensity is E0 = 1000 V/m. Determine the electric field intensity E between the capacitor plates at the capacitor edge
[a] ans
magnetic field Bo=0.5 T
now we find the intensity of magnetic field
intensity of magnetic field I=1/2Bo^2*c/
=0.5*(0.5)^2*(3*10^8)/4*3.14*10^-7
=375*10^5/12.56*10^-7
=29.9*10^12 W/m^2
[b] ans
now we find the intensity of electric field
intensity of electric field I=1/2*8.85*10^-12*1000^2*3*10^8
=13.3*10^2 W/m^2
