ELECTRIC FIELDS
How does the electric force of Coulomb's Law act at a distance?
Michael Faraday's answer was that the charge sets up an electric field in the space around it which affect other charges. Any change in the charge changes this field and takes time to occur.
ANY
VECTOR FIELD
IS A COLLECTION OF VECTORS WHICH
CHANGE IN MAGNITUDE AND DIRECTION ACCORDING TO
THE POSITION AROUND A DEFINED OBJECT.
THE
ELECTRIC FIELD
INDICATOR
IS THE
PROTON
! ALWAYS!
DEFINITION OF ELECTRIC FIELD:
>>>
E = F/q (test charge value)
ELECTRIC FIELD LINES EXTEND AWAY FROM
POSITIVE
CHARGE AND TOWARD
NEGATIVE
CHARGE.
Equation for the E Field of a point charge!
Michael Faraday was the originator of the idea of the electric field concept. He influenced James Clerk Maxwell and provoked him to consider new ideas. He is a very interesting person and physicist!
