This principle that alternating field gradients have a net focusing effect is called strong focusing.
This creates a high field gradient around the smaller, positively charged electrode.
The grad-B drift can be considered to result from the force on a magnetic dipole in a field gradient.
Then once the particles are saturated inside a target tissue, a magnetic field gradient is used to pull said entity away from its native environment.
Particles suspended in a liquid will be susceptible to the electrical field gradient, this is known as dielectrophoresis.
A large bushing can be a complex structure since it must provide careful control of the electric field gradient without letting the transformer leak oil.
Examples of inhomogeneous effects include a magnetic field gradient and a distribution of chemical shifts.
This electric field gradient continues up into the atmosphere to a point where the voltage reaches its maximum, in the neighborhood of 300,000 volts.
In the absence of magnetic field gradients, the equations describing the relaxation are:
Various strategies are used, from guard rings to overlaps of metallization to spread out the field gradient.
