If compass on is not heading to south or north, the stronger magnetic will help it quicker return to the position?
hi tor1chipI am worried about the not extremely way... There are two points I consider: 1) If the magnetic is stronger then the needle should be heavier. 2) if the magnetic is made by electricity, then the temperature on the needle will be higher, so making the magnetic weak. So the fastest returning may not by the extremely strong magnetic needle. So how strong is best?
