[QUOTE="UMath1, post: 5460317, member: 555974"] I am confused about how the magnetic field of a solenoid is calculated in this image.[ATTACH=full]100025[/ATTACH] Why is only the current going into the page included in calculating the magnetic field? Shouldn't the field be twice the amount calculated because there is a magnetic field generated by the part of the turns the bottom with current going out of the page? And I don't understand why the vertical components of the path are taken to be zero. Although it is said that the field is perpendicular, the diagram shows that there is a portion of the field parallel to the vertical path. [/QUOTE]
