and the following 1)Using the simulation you started in class (with q=1nC, m=1microgram, B_x=B_y=0, B_z=3e^(-(x/1m)^2), and a small enough dt) explore the range of motion that is possible with ||v_o||=1m/s and varying direction for initial velocity. report on all the qualitatively different behavior you see and the range launch angles over which you observe this behavior. 2)Find the vector potential due to a square loop of wire with sides of length w which carries a current I. | Feb. 28 | |

The loop should be 10cm on a side, have a mass of 20grams, a current of 0.5Amp with 200 turns and a magnetic field of .75 Tesla.

electron to a 1MHz wave polarized in the x-direction propagating in the z-direction. Determine its motion (I suggest a time step dt=1e-10s and drawing the electron with a 1cm radius). Watch the simulation for 50 oscillations of the wave and graph the work done on the
electron as a function of time for the last 3 oscillations. Repeat for two additional situations 1) with the electron subject to a linear damping force (Fd=-b*velocity) with b=1e-25kg/s and 2) with the same damping coeffient b=1e-25kg/s and a restoring force with spring constant 3e-17N/m.], 9.18, 9.20.a, (close date 4/29) Extra credit: Determine the steady state dipole moment amplitude for the electron in 9.11 pairing it with a proton (which was providing the restoring force) for a variety of frequencies between 100kHz and 10MHz and graph the amplitude of the dipole moment as a function of frequency, 11.3. | May 1 | |
