what happens when you randomly move the bar magnet roundabout and above the compass one foot or farther? Nearer than a foot?

Sagot :

When the bar magnet was moved around the compass one foot or farther away from the still compass on a horizontal surface, the compass needle slightly deflected clockwise or counterclockwise or nothing happened to it at all. For moving the bar magnet in circles a foot or farther above the compass, the compass needle slightly rotated in the same direction or nothing at all.
