electrostatic field

Thân thiện

A scientist uses a Van de Graaff generator to demonstrate an electrostatic field.

Definition

1. Noun:
   • Electric field associated with static electric charges: An electrostatic field is a region of space around electrically charged particles or objects where a force would be exerted on other charged particles. This field exists due to stationary (static) electric charges.

Usage Examples

• Noun:
  • The scientist measured the strength of the electrostatic field around the charged sphere.
  • An electrostatic field is responsible for the attraction between a balloon and a wall after rubbing it on your hair.
  • Understanding electrostatic fields is fundamental to the study of electromagnetism.

Advanced Usage

• "to map an electrostatic field": to determine the direction and strength of the field lines in a region.
  • The students used a probe to map the electrostatic field between the two plates.
• "the principle of superposition for electrostatic fields": the net field created by multiple charges is the vector sum of the fields created by each charge individually.
  • To solve the problem, we applied the principle of superposition for electrostatic fields.

Variants and Related Words

• Electrostatic (adj): relating to stationary electric charges or the forces between them.
  • Electrostatic forces can cause dust to cling to a screen.
• Electric field (n): a more general term for a field surrounding electric charges, which can be static (electrostatic) or changing.
  • A changing magnetic field can induce an electric field.

Synonyms

• Static electric field: A field produced by non-moving charges.
• Coulomb field: Specifically refers to the electric field generated by a point charge, as described by Coulomb's law.

Related Phrases

• Electrostatic field lines: Imaginary lines used to visualize the direction and strength of an electrostatic field.
  • The density of the electrostatic field lines indicates the field's intensity.
• Electrostatic field intensity/strength: A measure of the force per unit charge exerted by the field.
  • The electrostatic field strength decreases with the square of the distance from the charge.

Related Concepts
