Induced Electric Fields01:23

Induced Electric Fields

4.0K
The fact that emfs are induced in circuits implies that work is being done on the conduction electrons in the wires. What can possibly be the source of this work? We know that it’s neither a battery nor a magnetic field, as a battery does not have to be present in a circuit where current is induced, and magnetic fields never do any work on moving charges. The source of the work is in fact an electric field that is induced in the wires. For example, if a stationary conductor is placed in a...

Induced Electric Dipoles

4.5K
A permanent electric dipole orients itself along an external electric field. This rotation can be quantified by defining the potential energy because the external torque does work in rotating it. Then, the potential energy is minimum at the parallel configuration and maximum at the antiparallel configuration. While the former is a stable equilibrium, the latter is an unstable equilibrium.
Since the absolute value of potential energy holds no physical meaning, its zero value can be chosen as per...

Induced Electric Fields: Applications

1.9K
An important distinction exists between the electric field induced by a changing magnetic field and the electrostatic field produced by a fixed charge distribution. Specifically, the induced electric field is nonconservative because it does not work in moving a charge over a closed path. In contrast, the electrostatic field is conservative and does no net work over a closed path. Hence, electric potential can be associated with the electrostatic field but not the induced field. The following...

Electromagnetic Waves

9.6K
James Clerk Maxwell formulated a single theory combining all the electric and magnetic effects scientists knew during that time, calling the phenomena his theory predicted “Electromagnetic waves”. He brought together all the work that had been done by brilliant physicists such as Oersted, Coulomb, Gauss, and Faraday and added his own insights to develop the overarching theory of electromagnetism. Maxwell’s equations, combined with the Lorentz force law, encompass all the laws...

Electromagnetic Fields

2.3K
Electric fields generated by static charges, often referred to as electrostatic fields, are characteristically different from electric fields created by time-varying magnetic fields. While the former is a conservative field, implying that no net work is done on a test charge if it goes around in a complete loop in the field, the latter is, by definition, not a conservative field; net work is done, and it is proportional to the rate of change of magnetic flux.
However, the observation of...

Van der Waals Interactions01:24

Van der Waals Interactions

67.5K
Atoms and molecules interact with each other through intermolecular forces. These electrostatic forces arise from attractive or repulsive interactions between particles with permanent, partial, or temporary charges. The intermolecular forces between neutral atoms and molecules are ion–dipole, dipole–dipole, and dispersion forces, collectively known as van der Waals forces.

Area of Science:

  • Physics
  • Chemistry
  • Water Science

Background:

  • Water exhibits unique properties influenced by its structure.
  • Exclusion Zone (EZ) water, a distinct phase of water, shows altered characteristics compared to bulk or deionized (DI) water.
  • Electromagnetic fields can interact with water molecules, potentially altering their properties.

Purpose of the Study:

  • To investigate the effects of low-frequency electric fields on different water types (DI, EZ, bulk).
  • To determine if electric field exposure can induce changes in water's radiance and surface properties.
  • To explore the potential for creating EZ-like water from DI water using electric fields.

Main Methods:

  • Exposure of water samples to low-frequency electric fields using platinum electrodes.
  • Monitoring radiance changes with a spectro-radiometer.
  • Measuring contact angles and droplet charges with a contact-angle goniometer.

Main Results:

  • Electric field treatment caused a temporary drop in radiance for DI, EZ, and bulk water.
  • EZ and bulk water showed less radiance drop than DI water.
  • Electric field application induced differential charging in EZ and bulk water droplets.
  • Applying an electric field to DI water from above mimicked the radiance profile of EZ water.

Conclusions:

  • Low-frequency electric fields can alter water's optical and electrical properties.
  • Specific electric field configurations may induce molecular ordering in DI water, resembling EZ water.
  • The position of electrodes relative to the water sample influences the interaction with electric fields.
