3. (i.) Sunlight delivers 2.63x108 W/m² to the surface of Venus. If the rms magnetic field strength is about 3.32x10-6 T, what is the rms value of the Sun's electric field? (a) 9.95x107 N/C (b) 3.17x107 N/C (c) 2.49x107 N/C (d) 6.34x107 N/C (e) None of the above (ii.) What does the magnitude of the Poynting vector represent? The direction?

QB2d. Calculate the EMF induced in the railway carriage wheel of radius R=840 mm by the magnetic field of the Earth. Consider that the magnetic field of the Earth makes an angle of 71.5 deg with the horizontal surface of the railway track. Take the speed of the carriage to be v = = 158 km h¹ and the value of the magnetic field of the Earth B = 10-5 T. Provide your answer in microvolts (10-6 V=1 μV): for example, if you calculated the value to be 0.000075 V, then enter 75 as your answer. Enter your answer in the box below.

A magnetic field of magnitude 0.52 T is directed vertically upward. (a) Find the magnetic flux through a flat surface of area 23 cm2 if the surface is vertical.(b) Find the magnetic flux through a flat surface of area 23 cm2 if the surface is horizontal.(c) Find the magnetic flux through a flat surface of area 23 cm2 if the surface is at angle of 67° with the horizontal.

A jet plane is travelling towards west at a speed of 1800 km/h. What is the voltage difference developed between the ends of the wing having a span of 25 m, if the Earth’s magnetic field at the location has a magnitude of 5×10-4 T and the dip angle is 30°.
