JERRY B. MARION, in Physics in the Modern World (Second Edition), 1981 Magnetic Field Strength The strength of an electric field is defined in terms of the force that is exerted on a charged particle in that field. We use the same procedure for defining the strength of a magnetic field....
But, in their cases at least, it was worth the money that they paid. Maybe magnetic lines of force aren't a magical cure all, but I think people should be able to make up their own minds about it. Byirontoenail— On Sep 10, 2011 ...
In this region, the magnetic flux density is changed locally and a strong magnetic field gradient is formed. The redox-reaction changes the magnetic susceptibility of the electrolyte near the electrodes, and the resulting magnetic field gradient exerts a force on the fluid, which leads to a ...

Spin-polarised electrons can be generated in NM materials using the following methods [9]: spin injection from a FM, a magnetic field, an electric field, electromagnetic wave introduction, Zeeman splitting, spin motive force, a thermal gradient and mechanical rotation (see Fig. 3). One of the...
