Suppose that a bar magnet is suspended by a string a few millimeters above another bar magnet. if the north pole of the bottom magnet is on the left, where is the north pole of the top magnet? explain.

The north pole of the suspended magnet will be towards the right side in reference to the north pole of the bar at the bottom.

Further Explanation:

A bar magnet has two poles named as the north pole and the south pole. The bar magnet does not have a magnetic monopole. It will always have a pair of the north pole and south pole.

The property of the magnetic poles is that the like poles repel each other and the unlike poles attract each other. It means that the north pole will be attracted towards the south pole and it will be repelled from the north pole.

When the bar magnet at the bottom is kept with is north pole pointing towards left, then the freely suspended bar magnet above it by means of a string will align itself such that its north pole is above the south pole of the mar magnet at the bottom.

It will be repelled from the north pole of the bottom magnet and the north pole of the suspended magnet will be towards the right side.

Thus, the north pole of the suspended magnet will be towards the right side in reference to the north pole of the bar at the bottom.

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2
