A plane monochromatic electromagnetic wave with wavelength λ=2.0cm, propagates through a vacuum. Its magnetic field is described by >B⃗ =(Bxi^+Byj^)cos(kz+ωt), where Bx=1.9×10−6T, By=4.7×10−6T, and i^ and j^ are the unit vectors in the +x and +y directions, respectively. What is Sz, the z-component of the Poynting vector at (x=0,y=0,z=0) at t=0?

Avery long solenoid of inner radius 2.75 cm creates an oscillating magnetic field of the form = for this solenoid, =0.00425 t and =319 rad/s. (a)what is the maximum value of the induced electric field at a perpendicular distance 1.45 cm from the axis of the solenoid? (b) what is the maximum value of the inducted electric field at a point 5.85 cm perpendicular from the axis of the solenoid?
