a particle of charge q and mass m is initially at rest at origin

A particle of charge q and mass m is subjected to an electric field E=E_(0)(1-ax^(2)) in the x - direction, where a and E_(0) are constants. Initially the particle was at rest at x = 0. Other than the initial position the kinetic energy of the particle becomes zero when the distance of the particle from the origin is :.

Larger micron-sized magnetite particles will also be magnetically non-uniform (multi-domain) when in zero-field conditions, as increasing size increases non-uniformity. However, applying a high enough strength magnetic field has the effect of saturating the particles as is shown ( Figure 1 d-i).

Magnetite - Wikipedia

Performance and mechanism of conductive magnetite particle-enhanced ...

Magnetite, as an iron oxide with high conductivity, could function as an electron transfer tunnel to achieve interspecies electron transfer between bacteria and methanogens. 27 Similar phenomena were found, where metallic oxide played a major role of electron carriers in DIET by transferring the electrons to methanogens in the AD process. 28

Magnetic Particles : Particles and Kits for Magnetic separation - chemicell

Magnetic properties. Magnetic particles for bioseparation consist of one or more magnetic cores with a coating matrix of polymers, silica or hydroxylapatite with terminal functionalized groups. The magnetic core generally consists either of magnetite (Fe 3 O 4) or maghemite (gamma Fe 2 O 3) with superparamagnetic or ferromagnetic properties.

What happens if a particle accelerator malfunctions

The Accident. That is because a Russian scientist named Anatoli Petrovich Bugorski, in the year 1978, working at U-70 synchrotron at the Institute for High Energy Physics in Protvino, accidentally put his head into a particle accelerator while checking for a dysfunctional part in the equipment. His head came in the path of a high-energy proton.

While large magnetite particles would sink quickly to the bottom due to gravity, the thermal agitation (Brownian motion) at room temperature is sufficient to keep these in colloidal suspension if they are small enough. This suggest that there might be some ratio of k B T with some expression of gravitational potential energy.
