... The Hall effect was discovered by Edwin H. Hall (1855–1938) when he was 24, in the course of working on his PhD dissertation in 1879. The Hall effect is best known for its use in probes for measuring B, but it also has many other uses. The Hall effect is a straightforward application of the Lorentz ...

Lecture 10 Induction and Inductance Ch. 30
... What is an inductor? An inductor is a piece of wire twisted into a coil. It is also called a solenoid. If the current is constant in time, the inductor behaves like a wire with resistance. The current has to vary with time to make it behave as an inductor. When the current varies the magnetic field ...

Neutron magnetic moment
The neutron magnetic moment is the intrinsic magnetic dipole moment of the neutron, symbol μn. Protons and neutrons, both nucleons, comprise the nucleus of atoms, and both nucleons behave as small magnets whose strengths are measured by their magnetic moments. The neutron interacts with normal matter primarily through the nuclear force and through its magnetic moment. The neutron's magnetic moment is exploited to probe the atomic structure of materials using scattering methods and to manipulate the properties of neutron beams in particle accelerators. The neutron was determined to have a magnetic moment by indirect methods in the mid 1930s. Luis Alvarez and Felix Bloch made the first accurate, direct measurement of the neutron's magnetic moment in 1940. The existence of the neutron's magnetic moment indicates the neutron is not an elementary particle. For an elementary particle to have an intrinsic magnetic moment, it must have both spin and electric charge. The neutron has spin 1/2 ħ, but it has no net charge. The existence of the neutron's magnetic moment was puzzling and defied a correct explanation until the quark model for particles was developed in the 1960s. The neutron is composed of three quarks, and the magnetic moments of these elementary particles combine to give the neutron its magnetic moment.
