You do'nt know a lot of thing. Euclid said, "There is no royal road to geometry". God helps those who help themselves. God can not help you, me neither. What you need is ten-years-hard-study by yourself.

Area is not a vector. Open any textbook that has vector > analysis within. Physicists have been doing vector-by-vector-division for a hundred years. The equation of magnetic force is "vector division by vector". F=iLXB (X is corss product). L is a length vector; assuming L=l <i>m, <i> is a 3D unit vector. B is magnetic flux density. Its unit is tesla, or Wb/m^2. Wb, Weber, is the unit of magnetic flux. Assuming B= b <j>(Wb/m^2), <j> is a 3D unit vector. Since B is a vector of surface density, we can rewrite it: B= (b/<j>) (Wb/m^2), <j> is moved to denominator. LXB= l <i> X b <j> m(Wb/m^2) = (lb<i> / <j>) (Wb /m) It's VDV. |
