How does magnetic fields work?

There are a lot of people who are interested in magnetic fields. If you would like to test magnetic fields, you can do this with the help of permanent magnets. It has always been said that the earth has one big magnetic field.

There are times when the magnetic field can become more prominent depending on the earth’s movement. Magnetic fields are important because they are able to deflect the solar wind that can be very harmful to the earth. If the solar wind would continuously strike the earth, there is a very big chance that the ozone layer will be stripped off and people will not be protected.
