Science (New York, N.Y.)
|September 26, 1986
Resumen
Los experimentos muestran que la polaridad de la carga atmosférica influye en la formación de rayos. Al invertir la carga de aire, los científicos crearon nubes de tormenta anormalmente polarizadas, lo que sugiere que las cargas atmosféricas iniciales determinan la polaridad del rayo.
Área de la Ciencia:
- Ciencias de la atmósfera Ciencias atmosféricas.
- El electromagnetismo es el electromagnetismo.
- Física de las nubes Física de las nubes.
Sus antecedentes:
- La formación de rayos implica complejos procesos de electrificación dentro de las nubes eléctricas.
- El papel de la polaridad de carga atmosférica preexistente en la iniciación y determinación de la electrificación de las nubes sigue siendo un área de investigación.
Objetivo del estudio:
- Investigar si la polaridad de las cargas atmosféricas influye en los procesos de electrificación que conducen al rayo.
- Para determinar el impacto de la carga espacial manipulada en el desarrollo y la polaridad de la nube de tormenta.
Principales métodos:
- Los experimentos realizados en Nuevo México utilizaron un cable electrificado a través de un cañón para revertir la carga espacial positiva natural en el aire sub-nube.
- Las observaciones se centraron en la polaridad resultante de las nubes que se formaron y se electrificaron sobre la masa de aire modificada.
Principales resultados:
- En múltiples ocasiones, las nubes que se formaban sobre el cable electrificado exhibieron una polaridad anormal, con cargas positivas dominantes en la región inferior de la nube, contrariamente a las cargas negativas típicas.
- La inversión de la carga espacial natural condujo a la formación de nubes inusualmente electrificadas.
Conclusiones:
- El estudio sugiere que el proceso de electrificación en las nubes eléctricas puede ser iniciado por factores externos.
- La polaridad de la electrificación de las nubes parece estar significativamente influenciada por las pequeñas cargas presentes en la atmósfera antes del desarrollo de las nubes.

01:29Potential Due to a Polarized Object
A neutral atom consists of a positively charged nucleus surrounded by a negatively charged electron cloud. When placed in an external electric field, the external electric force pulls the electrons and nucleus apart, opposite to the intrinsic attraction between the nucleus and the electrons. The opposing forces balance each other with a slight shift between the center of masses of the nucleus and the electron cloud, resulting in a polarized atom. On the other hand, a few molecules, like water,...
01:30Electric Field of Two Equal and Opposite Charges
Atoms generally contain the same number of positively and negatively charged particles, protons, and electrons. Hence, they are electrically neutral. However, the centers of the positive and negative charges do not always coincide. In such a scenario, the electric field of an atom may not be zero.
A separation of the positive and negative charges can lead to a weak, remnant effect of the positive and negative charges. The expectation is that the more the distance between the positive and...

01:31Dielectric Polarization in a Capacitor
The presence of a dielectric medium in a capacitor not only changes the voltage and capacitance but also affects the electric field. In general, dielectrics can be of two types: polar and nonpolar. In a polar dielectric, the positive and negative charges in the molecules are separated by a distance and hence have a permanent dipole moment. In contrast, no such charge separation exists in a nonpolar dielectric, however the nonpolar molecules get polarized in the presence of an external electric...
01:16Equipotential Surfaces and Conductors
For a conductor in which all charges are at rest, the conductor's surface is equipotential. The electric field is always perpendicular to equipotential surfaces. Therefore, in a conductor with static charges, the electric field just outside the conductor is always perpendicular to the conductor's surface. Any tangential component of the electric field will cause charges to move inside the conductor, which will violate the electrostatic nature of the system. In an electrostatic situation, if a...

From lightning during thunderstorms to electronic devices, the phenomenon of electromagnetism is all around us. The electromagnetic force is one of the four fundamental forces of nature. It has been known to humanity in various forms for thousands of years. For example, the ancient Greek philosopher Thales of Miletus recorded his experiments on static electricity using amber and fur in the sixth century BC.

01:15Charging Conductors By Induction
The Earth is a good conductor of electricity, and it is so big that it can be considered an infinite source or sink of charges. It can easily exchange charges with any matter.
Generally, conductors like metals do not allow any excess charge to be present on them. Any excess charge added to metals easily flows away, for example, when a metal is placed on the Earth. This process is called earthing.
However, conductors can be charged by a process called induction. For example, consider charging a...
