Question

Three identical iron bars are kept on a table. Two out of three bars are magnets. In one of the magnets, the north-south poles are marked. How will you find out which of the other two bars is a magnet? Identify the poles of this magnet.

Answer 1

Magnetic poles:

1. The magnetic pole is the region at each end of a magnet with the strongest external magnetic field.
2. Magnet poles may refer to a magnetic monopole, a hypothetical elementary particle.
3. Magnet poles are magnetically strong areas of a magnet. When we have multiple magnet poles, they repel, pull, or attract each other. Like poles repel each other while opposite poles always attract each other.
4. Magnetism refers to these acts of attraction and repulsion. Magnetism refers to the magnetic space around a magnet.

Experiment:

1. Take the magnet with the marked North-South poles.
2. Keep it close to both iron bars, and both will be drawn to it because they are magnetic.
3. So, for the repulsion test, test each of the two magnet bars one by one.
4. Magnets both attract and repel, whereas iron only attracts.
5. Thus, repulsion helps to find which one is the bar and which one is the magnet.
6. Also, the repulsion of the magnet (where the poles are marked) with other magnets shows the poles of the magnet as the north pole of first magnet will repel the north pole of the second magnet and vice versa.
