field gradient

This creates a high field gradient around the smaller, positively charged electrode.

In practice instruments could not survive such a journey; they would be torn apart by the increasing gravitational field gradients.

The grad-B drift can be considered to result from the force on a magnetic dipole in a field gradient.

Various strategies are used, from guard rings to overlaps of metallization to spread out the field gradient.

It includes the application of magnetic field gradient pulses to select specific coherences.

This principle that alternating field gradients have a net focusing effect is called strong focusing.

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.

In the absence of magnetic field gradients, the equations describing the relaxation are:

Some authors suggest that these abilities may be explained by postulating human sensitivity to small magnetic field gradient changes.

Particles suspended in a liquid will be susceptible to the electrical field gradient, this is known as dielectrophoresis.

A number of schemes have been devised for combining field gradients and radio frequency excitation to create an image:

A pulsed field gradient is a short, timed pulse with spatial-dependent field intensity.

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.

Examples of inhomogeneous effects include a magnetic field gradient and a distribution of chemical shifts.

The rapid switching on and off of the magnetic field gradients is capable of causing nerve stimulation.

These nappes show a Barrovian field gradient.

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.

The narrowest point of the focused beam, known as the beam waist, contains a very strong electric field gradient.

The first derivatives of the field, or the second derivatives of the potential, is the electric field gradient.

Pulsed field gradient NMR experiments can be used to measure diffusion constants.

As the edges of the Schottky contact are fairly sharp, high electric field gradient occurs around them which limits the reverse breakdown voltage.

If several spatially distributed charges generate such an electric potential, e.g. in a solid, an electric field gradient may also be defined.

Field homogeneity is measured by examining an FID signal in the absence of field gradients.

The readings are subtracted in order to measure the difference between the sensed magnetic fields, which gives the field gradients caused by magnetic anomalies.

The latter question is important in deciding whether the potentially large impressed field gradients induced by ultrasound are truly an advantage in effecting stimulation.
