3. Question Details Electromagnetic radiation is moving to the right, and at this time and place the electric field is horizontal and points out of the page (see the figure). The magnitude of the electric field is E 3000 N/C Direction of propagation What is the magnitude of the associated magnetic field at this time and place? what is the direction of the associated magnetic field at this time and place? Select B out of the page k into the page d 0m zero magnitude 4. Question Details A long aluminum tube sits on the table. A strong electro-magnet under the table creates a magnetic field that points down and is increasing (a) What is the direction of the change in magnetic field vector? down (into the table) O up (from the table) O 0 (no change) (b) Looking down at the tube from above, does the non-Coulomb electric field curl clockwise or counter- clockwise? clockwise counter-clockwise no curly E

Explanation / Answer

Problem 3)

Given

Electric field E = 3000 N / C

Required magnetic field B = E / c

Where c = speed of EM radiation = 3 * 10^8 m / s

Plug the values we get B = 0.00001 T

= 10 µT
