Okay so this is a theory question from a more advanced question.Idon't want more help on the question than answering thefollowing(because I understand the rest of it already, but I wantto clarifysomething for myself).
So You have a loop of wire, 103 turns. 10 A going through thisloop.You are told to find the magnetic field at a point that is.21 moutward on its axis (axis is perpendicular to the circle). SoIwould use: dB=(u0)/4pi * Int((I*ds x r^)/r^2) wherer^is the unit vector for r, which, for example at the top oftheloop, would be downward and outwards towards that point ontheaxis... If this is the case, SEE MY ATTACHED DIAGRAM: Isthemagnetic field dB from that small portion at the top o theloop , really pointing in the direction as indicated on the diagram?Ijust want to be sure I have this right
