=1 The neutron is a particle with zero charge. Nonetheless, it has a nonzero magnetic moment of 9.66×10−27A⋅m2. This can be explained by the internal structure of the neutron. The neutron is composed of three fundamental particles called quarks: an "up" (u) quark, of charge +2e/3, and two "down" (d) quarks, each of charge −e/3. The combination of the three quarks produces a net charge of 2e/3−e/3−e/3=0. If the quarks are in motion, however, they can produce a nonzero magnetic moment. As a very simple model, suppose the up quark moves in a counterclockwise circular path inside the neutron while the down quarks move in a clockwise circular path, all of radius r and all with the same speed v.
(c.) Using the figure as a reference, what is the direction the magnetic moment created by the circulating u quark? (d.) What is the equation and direction of the magnetic moment created by one of the circulating d quarks? (Be careful with your signs here.) (e.) What is the equation and direction of the magnetic moment for entire the three-quark system? (f.) With what speed v must the quarks move if this model is to reproduce the magnetic moment of the neutron? Use r=0.8×10−15 m (a typical value given for neutron's radius) for the radius of the orbits.
