... field at P due to strip A is B1 and that due to strip C is B2. The resultant of these two is parallel to the width AC of the sheet. The field due to the whole sheet will also be in the same direction. The field on the opposite side of the sheet at the same distance will also be of the same magnitude ...

Magnetism Review Answers
... When electricity goes through the wire, the coil of wire becomes an electromagnet and interacts with the magnet’s magnetic field. The wire then spins. Every 180o the current reverses direction so that the wire keeps spinning and spinning. (Electromagnet’s magnetic field also keeps reversing.) ...

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.
