Neodymium magnets<\/a><\/li>\n<\/ul>\nThe magnetic force is sometimes the great unknown force, as it is not as present in our daily lives as gravity would be with all of Newton's mechanics. Nevertheless, the magnetic force is one of the main and most important forces. On the one hand for the generation of electricity and on the other hand the magnetic field around the Earth is what protects us from radiation that would otherwise be deadly.<\/p>\n
MAGNETIC FIELD LINES EXPERIMENT STEP-BY-STEP<\/h2>\n
In this experiment we are going to place a magnet underneath a piece of paper. Remember that the magnet will have a North Pole and a South Pole, and there must be a certain distance between the poles, as the lines of force will go from North to South. This means that with a very flat and thin magnet you will not be able to do the experiment well, as the North and South poles will be too close together and you will not be able to see the experiment well. You can always join several thin flat magnets together, so that you increase the distance between the poles.<\/p>\n
STEP 1.<\/strong> We place our neodymium magnet under a white piece of paper.<\/p>\n
<\/p>\n
STEP 2.<\/strong> Then, slowly pour the iron filings on top of the paper.<\/p>\n
<\/p>\n
<\/p>\n
STEP 3.<\/strong> You will be able to see how the iron filings form lines on the surface of the paper that will be similar to the lines of the earth's magnetic field that you may have seen at some point in your life.<\/p>\n <\/p>\n

TECHNICAL EXPLANATION<\/h2>\n
The technical explanation of this experiment is very simple. Here, since it is the magnet that is attracting the iron, and it does so through its lines of force, the iron filings will be placed inside the lines of action of the magnet, drawing in which direction these magnetic forces go.<\/p>\n
