A neutral hydrogen atom in its normal state behaves like an electric charge distribution that consists of a point charge of magnitude surrounded by a distribution of negative charge whose density is given by . Here m is the Bohr radius, and is a constant with the value required to make the total amount of negative charge exactly . What is the electric field strength for radius ? What is the electric field strength at radius ? We were unable...

The energy of a magnetic moment in a magnetic field is . A certain paramagnetic salt contains 1025 magnetic moments per m3. Each one has a value , due to the atom's spin. As the spin is 1/2, there only are two possible states and the magnetic moments can be parallel or antiparallel to the field. Each magnetic moment belongs to one distinguishable atom. A 1 cm3 sample of this salt is placed in a electromagnet producing a uniform magnetic...

Problem 22.17 (Multistep)
A coil of wire is connected to a power supply, and a current
runs in the coil. A single loop of wire is located near the coil,
with its axis on the same line as the axis of the coil. The radius
of the loop is 3 cm.
At time t1 the magnetic field at the center of the loop, due to the
coil, is 0.6 T, in the direction shown in the diagram; the current
in...

The behavior of a spin-
particle in a uniform magnetic field in the z-direction,
, with the Hamiltonian
You found that the expectation value of the spin vector
undergoes Larmor precession about the z axis. In this sense, we can
view it as an analogue to a rotating coin, choosing the
eigenstate with eigenvalue
to represent heads and the eigenstate with eigenvalue
to represent tails. Under time-evolution in the magnetic field,
these eigenstates will “rotate” between each other.
