... intergranular current compared to the intragranular value. Such a measurement (Fig. 3(a)) carried out on the Dy123 sample exhibits a very smooth inflexion point at µ0HAC ≈ 80 G but does not show clear features pointing to either inter- or intra-grain origin, even for AC inductions as large as 300 G. ...

Exercise 5 Solution
... At O, the velocity is zero, so there is no cutting of magnetic field lines, hence no emf is induced. When the bar swings down, PE is changed into KE, so the speed is increasing, hence the cutting of magnetic field lines is increasing, so induced emf is increased. When the bar swings down after reach ...

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.
