Difference btw induced and static electric field.

Click For Summary
SUMMARY

The discussion clarifies the distinction between induced and static electric fields, highlighting that ∇x E≠0 for induced fields and ∇x E=0 for static fields. Despite this difference, both types of electric fields exert forces on charges according to the equation F_e = q E. In the context of relativity, the distinction is less significant as both fields are combined in the electromagnetic field tensor during Lorentz transformations, emphasizing their collective influence on charged particles.

PREREQUISITES
  • Understanding of vector calculus, specifically curl operations (∇x E).
  • Familiarity with electric field concepts and their properties.
  • Knowledge of the Lorentz transformation in the context of special relativity.
  • Basic understanding of the electromagnetic field tensor.
NEXT STEPS
  • Study the mathematical implications of curl in vector fields.
  • Explore the properties and applications of the electromagnetic field tensor.
  • Learn about the Lorentz transformation and its effects on electric and magnetic fields.
  • Investigate the practical applications of induced electric fields in technology.
USEFUL FOR

Physicists, electrical engineers, and students studying electromagnetism and special relativity will benefit from this discussion, particularly those interested in the nuances of electric field behavior and their applications in various contexts.

∇x E≠0 for an induced electric field whereas for field produced by static charges we have ∇x E=0.
This is a very huge difference in the property of a vector field,then why do we call both of them electric field ?

They both exert forces on charges according to ##{\vec F}_e = q \vec E##.

Also, in relativity we don't distinguish between the two kinds of electric field when transforming from one reference frame to another via the Lorentz transformation. In the electromagnetic field tensor, it's always the sum of the two (i.e. the total electric field) that appears.

you could call them different things, but they exert forces the same way so it's convenient to just add them up.
