Magnetic Dipole Moment of a Neodymium Magnet The Experiment
... The dipole moment of a magnet has its origins in the motion if the electrons in the material. Electrons orbits a nucleus, for example, act somewhat like a current going round a tiny circular circuit. For a variety of reasons (mostly quantum mechanical) the dipole moment of an atom is rarely much big ...

Chapter 6 Maxwell`s Equations for Electromagnetic Waves
... In 1864, James Clerk Maxwell published a paper on the dynamics of electromagnetic fields, in which he collected four previously described equations which relate electric and magnetic forces, modified one (by adding a term to remove an inconsistency), and combined them to demonstrate the true nature ...

Drifting Continents and Spreading Seas
... Using the magnetism recorded in ancient rocks, we can construct a history of how the magnetic poles have moved relative to that rock through time (or is it how the rock has moved relative to the magnetic poles through time?) ...

Equivalent isotropically radiated power
... The antenna and its image form a dipole that radiates only upward. The quarter wave antenna or quarter wave monopole is a whip antenna that behaves as a dipole antenna. It is formed by a vertical wire in length. It is fed in the lower end, which is near a conductive surface which works as a reflecto ...

The Magnetic Field
... • We can define a magnetic field B at a point in space in terms of the magnetic force FB that the field exerts on a charged particle moving with a velocity v. • Experiments on charged particles moving in a magnetic field give the following results: – The magnitude FB of the magnetic force exerted o ...

MRI. Thermography. - med.muni
... For H nuclei in the lower energy state to move to the higher energy state RF pulses of frequency equal to the Larmor frequency must be transmitted towards the patient using a transmitter coil (hence the ‘resonance’ in MRI). When this occurs the nuclei are also forced to precess in phase. Longitudina ...
