... only charged particles can exert them or feel them. But magnetic forces, unlike electric forces, act on charges only when they are moving, and rather than attracting or repelling them, they push them sideways. The magnetic force on a moving charge is always at right angles to the motion of the charg ...

Electric and magnetic field variations arising from the seismic dynamo... for aftershocks of the M7.1 earthquake of 26 May 2003
... During the observation period, we could detect MT signals for 27 aftershocks with magnitudes ranging between 2.8 and 4.1. In this section, we show relations between the electric and magnetic signals with the ground velocity data obtained at the KKWH station. Figure 7 shows the relation between 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.
