... transverse nuclear polarization or ``free induction decay'' of nuclear polarization. • Here an RF pulse is applied to rotate nuclear spins from the direction of the local magnetic field . When the RF field is switched off, nuclear spins perform a free precession around the local field and relax back ...

ELECTROMAGNETIC FIELDS (EMFs)
... Everyone is exposed to EMFs. Electric and magnetic fields are part of life's natural environment. The Earth itself constantly generates a magnetic field which is substantially more intense than those found in most workplaces or residences. Electrical and magnetic fields are continuously generated by ...

Brief History of Electromagnetics
... • Self-taught English chemist and physicist discovered electromagnetic induction in 1831 by which a changing magnetic field induces an electric field • “Distinct conversion of magnetism into electricity” (Faraday) ...

ELECTROMAGNETISM
... At this stage, you understand roughly as much about the classification of interactions as physicists understood around the year 1800. There appear to be three fundamentally different types of interactions: gravitational, electrical, and magnetic. Many types of interactions that appear superficially ...

... magnetic field is increased, however, the conductance decreases to e 2 /h as the spin polarization reaches unity. Proper configuration of the quantum point contact is important for operation of the spin filter. In Fig. 2, for example, by setting the initial energy such that the lowest subband was fu ...
