Take a magnetic compass.we know its north pole and south pole.now bring one end of a magnet to the north pole of magnetic compass ,if they repel each other , that is north pole.but if they attract .that is south pole
Comments

disadvantage is less magnetic effect, poles are identify in such a way that same charge repel each other an d different charges attract each other.

Happy studying!

1. Lodestone. Disadvantages: Limited number of uses as they can't be present according to our requirements. Their strength can't be increased or decreased as per requirement. They can't be switched on or off when required. 2. Take a magnetic compass and place it close to but not touching your magnet....

1. Lodestone. Disadvantages: Limited number of uses as they can't be present according to our requirements. Their strength can't be increased or decreased as per requirement. They can't be switched on or off when required. 2. Take a magnetic compass and place it close to but not touching your magnet. Watch carefully at where the compass needle points. The point that normally points to the north pole of Earth should point to one end of the magnet. That end is actually the South pole of the magnet. read less

1. Lodestones. As they are irregular in shape, they do not behave as expected in a uniform magnetic field. 2. Suspend it with a string. The pole pointing towards north is the north pole.

Hang up the magnet by a cotton thread so that it hangs freely. When it comes to rest, we notice that the magnet is lying in a North - South direction.

Ans 2.Suspend the bar magnet freely using a thread. The magnet will point in Geographical North South direction. The end pointing towards Geographical North is the North Pole of the magnet and the end pointing towards Geographical South is the South Pole of the magnet.

Disadvantage of using bar magnet is that its strength decreases as time spends due to wear and tear.Also they are not found in fixed shape.
