# What happens when you randomly move a bar magnet roundabout and above the compass one foot or farther nearer than a foot

THATS ALL YOU NEED

As you hover a magnet to a compass you see the needle of the compass to move the same way as you would move the magnet. However when you move the magnet away from the compass the magnetic field which affects the movement of the needle may deminish and eventually loose its influence on the compass.

Explanation:

Varying the distance of the magnet to an object affects the degree of either attraction or repulsion via the magnetic field. The closer the magnet is, the stronger the influence of the magnetic field. The farther the magnet is, the weaker the magnetic field becomes.

It move fast because the magnet has a lot force so it move fast
Move away to each other
Nothings happen because it is too far from the magnet except you will use a strong maganet bec. strong magnet can attract a material even if it's far
Nothings happen,Â except you will use a strong magnet because strong magnet can attract a magnetizable materials even it is nearer to the the magnet
On exploration of the compasses ability to indicate the magnetâ€™s strength:
â€¢ For button compasses: 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.
â€¢ For button compasses: But when the bar magnet was moved around the compass nearer than a foot from the compass, the
compass needle deflected clockwise or counterclockwise more noticeably. For moving the bar magnet in circles nearer than a
foot above the compass, the compass needle rotated more easily in the same direction as the rotating magnet.
â€¢ For bigger compasses that has magnetic needles twice as long as that of the button compasses, the above observations are
much more noticeable even at a two - feet separation from the same magnet. This suggests that the longer needle has greater
attractive or repulsive interaction with the magnet.

On exploration of the compasses ability to indicate the magnetâ€™s polarity:
â€¢ For all noticeable deflections, when the north end of the bar magnet is brought near the south end of the compass needle, the needle
is attracted and moves towards the magnet. So when the magnet is moved around the compass in whatever direction, the compass
needle follows with it.
â€¢ But when the north end of the bar magnet is brought near the north of the compass needle, the needle rotates away from the magnetâ€™s north end due to repulsion until the south end of the compass needle is nearest the north end of the magnet.

^_^
The compass needle would likely to follow to the direction of the bar magnet, and the point of the needle would vary to the polarity of the magnet facing the compass. Ex if the North part of magnet is being pointed, the south part of the needle would respond.
The compass will attract the magnet ..
The magnet field started to take over,pulling the needles slightly away from north.
