Scientific Data and Analysis

“Science is built up with facts, as a house is with stones. But a collection of facts is no more a science than a heap of stones is a house.” - Jules Henri Poincare

What Are Magnetic Fields It?


Forces can be applied at a distance through magnetism and static electricity. A magnet is an object that can attract some metals like iron. Static electricity can also attract objects without touching them, but it works a bit differently. It can attract and repel due to electrical charges.


All magnets produce a magnetic field. All magnets have a north and south pole. Magnetic poles are the strongest parts of a magnet. North and south poles of magnets attract each other. The two south poles and the two north poles repel each other. A magnetic field is the area around a magnet that attracts and repeal objects. If you place an object inside the magnet’s field, it will be attracted to the magnet. The simplest way to see a magnetic field is to sprinkle iron filings around a magnet. 

. Iron filings are tiny pieces of iron. When sprinkled around a magnet, they reveal the magnetic field. The Earth also has a magnetic field - it is like a huge magnet. Compasses work because the needle inside the compass is a magnet. One side of the needle is the north pole and the other side of the needle is the south pole. The north pole of the needle is attracted to the North Pole and the south pole of a needle is attracted to the South Pole.

The Closer The Magnets Are-The Stronger The Force

Magnetism works over a distance. However, the closer the objects are to each other, the stronger the magnetic force. If you try to pull magnets apart it is very hard because the magnets are so close to each other. Once you get them a little bit apart it is much easier.
