The active force can be applied to many aerodynamics systems and it is result of the pressure difference from the medium to the system.
Brown did not explain the reason of the force, so we have chance to suppose that this force is result of the asymmetry in orbital motion of the electrons in the dielectric atoms due to the electric field between the plates.
Lorenz force also can be considered as result of some gradient in the ether, Fig.2.3.

A wire carrying an electrical current, when in a magnetic field, experiences a force perpendicular to the direction of the current and the direction of the magnetic field.
This is the principle behind the operation of an electric motor, where fixed magnets create a magnetic field, and a coil of wire is carried upon a shaft that is free to rotate.
When electricity is applied to the coil of wire a current flows, causing it to experience a force due to the magnetic field; the wires of the coil are arranged such that all the forces on the wires act to make the shaft rotate, and so the motor runs.

 Electromagnetic Gravitational Interaction
In the presence of electric potential the Lorenz force influences the gravitational masses of the rollers.
The Lorenz force is directed transversely to the velocity along the cycloid and in the direction of the field B.
The value of the Lorenz force depends on the electrical potential, magnetic intensity, mass of the rollers and their traverse speed.

However, the force of an electric field on a charged particle is \mathbf{F} = q \mathbf{E} , and this force is independent of the velocity of the particle, which means that the particle will accelerate continually in the direction of the field.
The speed of light is invariant under a Lorenz transformation, but the velocity of light is changed.
The tensor character of this combined electromagnetic field implies that the field is anisotropic with respect to the velocity of the charged particle on which it produces a force: the Lorenz force varies with the velocity of the charged particle.

 Eliminating hard water scale: News from Environmental Treatment Concepts
The atomic force microscope (AFM), capable of examining growth patterns on surfaces at the highest resolution, is a tool that can demonstrate some of the key interactions.
A Lorenz force F is experienced by charged particles that flow through a field: F= qE + q (V x B) where q is the charge on the particle, E is the electric field vector, V is the particle velocity, and B the magnetic field vector.
This suggests the key performance parameter is the total value of the "Lorenz" force acting on the charged particles, rather than the individual magnetic and electric field vectors.

A new class of force sensors is introduced that is suited to human-robot interaction.

The effect of the Lorenz force is therefore to cause rotation of the solution about an axis parallel to the magnetic field.  This is illustrated in Figure 3 for fields parallel and perpendicular to the electrode surface.
Schematic diagram of the effect of the Lorenz force on solution flow around a disk electrode (see Figure 2) when a magnetic field is applied (a) parallel and (b) perpendicular to the electrode surface.
This suggests that the Lorenz force action found in the bulk solution (Figure 10) is not sufficient to cause changes to the current voltage characteristics.  Instead, it is likely that the field gradient force causes the stirring in the cavity observed for iron (Video 15).

 What Is MHD   (Site not responding. Last check: 2007-10-14)
The fact that the Lorenz force is opposite for ions and electrons gives rise to a bulk ``magnetic force'' whenever the current flows across magnetic field lines.
Now, the force is given by the third direction: J-cross-B, and this points inward towards the axis of the current column, acting to confine the plasma.
The full range of MHD phenomena extends as well to instabilities and turbulence, but this picture of force balance is what is behind the idea of a magnetically confined plasma, one example of which is the ``tokamak''.

It can, perhaps, best be explained by realizing that the force is really between the (moving) charged particle producing the field and the (moving) charged particle acted on by the field.
In fact, this problem was a main impetus for Lorenz and Einstein to develop the theory of special relativity.
If you watch the particles flying by, Einstein says their clocks slow down and they are repelled more slowly, which is another way of saying the magnetic attraction slows their motion apart induced by the electrostatic repulsion.

 Metering International - The only international publication covering all aspects of utility metering
Under extreme overloads there is a risk that the contacts will be forced apart, and the resultant sparking and local heating could destroy the switch.
To prevent this, the moving blade actuator must supply a much greater force than is necessary for normal loads, placing heavy demands on the actuator drive.
This arrangement minimises the force required from the actuator, so the solenoid draws relatively little power during operation and is typically driven by a low-voltage DC supply.

 Curatronic: Pulsing Electromagnetic Field Therapy (PEMF) or Pulsed Magnetic Field Therapy
The magnetic strength value of static magnets (expressed in Gauss value) is not relevant at all, since the measured field strengths of permanent magnets range from 300 gauss to 16000 gauss at the surface, at 2 cm distance around 10 gauss and at 10 cm distance absolutely nothing.
As result of induced Lorenz force pulsing electromagnetism will produce electricity in cells and this is the basis for Pulsing Electromagnetic Field Therapy.
The combined effects of electric and magnetic force explain that pulsing electromagnetic fields induce electrical changes on a cellular level within the body and cell metabolism is influenced.

 [79.11] Intergalactic Dust   (Site not responding. Last check: 2007-10-14)
Gravitational force from the stellar, dust and gas disk as well as the dark matter halo exerts a downward force.
This, together with the fact that (1) very small grains (with small radiation pressure efficiencies) are not well coupled to starlight; (2) for large grains the radiative force to the gravitational force is approximately inversely proportional to grain size, acts as a size ``filter'' for dust leaking into the intergalactic space.
Since the radiation pressure efficiency and the grain destruction rate are sensitive to dust composition, the relative importance of carbon dust compared to silicate dust expelled into the intergalactic space differs from that in the galactic plane.

By Andrew Koch, JDW Bureau Chief, Washington, DC High-powered lasers that knock cruise missiles and aircraft out of the sky, precision-guided projectiles that emerge from the exoatmosphere at a speed of M5.0, striking their targets with such force that explosive warheads are not required.
Perhaps the most revolutionary system is the electromagnetic (EM) railgun, which could deliver a strike similar to that of a meteorite, according to one navy official under Adm Mathis.
Unlike conventional guns - which use propellant to create expanding gases that force a projectile down a barrel - EM guns use electrical current to create an electromagnetic force (a Lorenz force) to propel the projectile between two conducting rails, the official explained.

When energetic charged particles travel through matter, the Coulomb force between the particles and the atomic nuclei in the medium leads to a large number of small deflections of the particle trajectories.
The nature of the Coulomb interaction leads to a cross section for scattering that is not integrable, but, in aggregate, the multiple scattering of a particle can be treated analytically.
Charged particles are bent by the Lorenz force in a magnetic field.
