which conditions are desired when drawing an amperian loop to find the magnetic field at p. select all that are true. wherever the magnetic field is parallel to the loop, it is also constant. the loop is parallel or perpendicular to the magnetic field at all points on the loop. the path of the loop is parallel to the magnetic field at p. the loop encloses some of the current that is contributing to the magnetic field. wherever the magnetic field is perpendicular to the loop, it is also constant. the path of the loop is perpendicular to the magnetic field at p. the path of the loop passes through the location p. the location p is on the interior of the loop
