Question

For static fields, the curl of E will be

(a) Rotational

(b) Irrotational

(c) Solenoidal

(d) Divergent

I have been asked this question during a job interview.

I would like to ask this question from Maxwell Law in Time Static Fields topic in section Maxwell Equations of Electromagnetic Theory

Answer 1

Correct answer is (b) Irrotational

The explanation: For static fields, the charges will be constant and the field is constant. Thus curl of the electric field intensity will be zero. This implies the field is irrotational.
