WebNov 16, 2024 · In this section we are going to introduce the concepts of the curl and the divergence of a vector. Let’s start with the curl. Given the vector field →F = P →i +Q→j +R→k F → = P i → + Q j → + R k → the curl is defined to be, curl →F = (Ry −Qz)→i +(P z −Rx)→j +(Qx−P y)→k curl F → = ( R y − Q z) i → + ( P z − R x) j → + ( Q x − P y) k → WebYes, curl indeed is a vector. In the x,y plane, the curl is a vector in the z direction. When you think of curl, think of the right hand rule. It should remind you of angular momentum, who's vector direction is in the direction perpendicular to the plane of rotation. ( 10 votes) Upvote Downvote Flag Akshat Jha 6 years ago Around 4:00
