Homework PHYS4315

 

Wednesday 1-20-2015: Study chapter 5 pages 210-223 and work homework assignment 5_1.

Monday 1-25-2015: Study chapter 5 pages 223-241 and work homework assignment 5_2.

Wednesday 1-27-2015: Study Chapter 5 pages 241-248 + handout on relativity. + work homework assignment 5_3.

Monday 2-2-2015: Reading assingment 249-255 + work assignment 5_4. Note that to work the problems for magnetic moment you have to study section 5.4.3 at home. The most important relations in this section are 5.85 and 5.86. Equation 5.86 gives the definition of the magnetic dipole moment. Note that a magnetic dipole consists of a current loop that carries a current I and has a surface area a. This could be an electron orbiting an atom, or just a spinning electron.Equation 5.86 gives the magnetic vector potential around a magnetic dipole m and is thus the equivalent of 3.102. Note that the electric potential around a electric dipole contains a dot product while the magnetic vector potential around a magnetic dipole moment contains a cross product. The electrostatic equivalent of 5.88 is 3.103. Both fields goe like 1/r^3.
