What is the relationship between electric force and electric field
... charged particles is perpendicular to both the electric field and its initial velocity. Also when drawing magnetic fields, they start at a north pole and head to a south pole. The magnetic force on a moving charge is perpendicular to the field. In electric fields, the force always points in the dire ...

... the speed of charges would have to be less than one millimeter per second to account for the field. Another possible cause for Earth’s magnetic field is convection currents from the rising heat of Earth’s core. Perhaps such convection currents combined with the rotational effects of Earth produce Ea ...

... Introduction to NMR Spectroscopy • In a magnetic field, there are now two energy states for a proton: a lower energy state with the nucleus aligned in the same direction as B0, and a higher energy state in which the nucleus aligned against B0. • When an external energy source (hn) that matches the e ...

... If a bulk conductor is present, we can induce currents to flow in the bulk conductor. Such currents are called eddy currents since they flow in circles. Demo: Try to place a copper sheet in between a pole faces of a magnet and/or try to pull it out. For example, in pulling it out, that part of the p ...

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.
