Curl is defined as the angular velocity at every point of the vector f

1.	Curl is defined as the angular velocity at every point of the vector field. State True/False.(a) True(b) FalseThis question was addressed to me during an interview.My doubt stems from Vector Calculus in portion Vector Calculus of Electromagnetic Theory
Answer» Right choice is (a) True To elaborate: Curl is DEFINED as the circulation of a vector per unit area. It is the cross product of the DEL operator and any vector field. Circulation implies the angular at every point of the vector field. It is obtained by multiplying the component of the vector PARALLEL to the specified closed path at each point ALONG it, by the differential path LENGTH and summing the results.
