It's only been recently that using magnets has come back into medical use no one exactly knows how the magnets promote healing, but it's theorized that magnets attract metal elements in the body, such as iron in blood, to increase blood circulation and therefore instigate healing. Venus will provide an important new perspective on the issue because like mars, it has no global magnetic field, yet it is similar in size to earth and has a much thicker atmosphere it will therefore provide unique data to help place the earth and mars results in context.

Try hanging a bar magnet in the air, and see how the north end of the magnet follows the direction towards the earth's north pole, and the south end of the magnet faces the south pole this is why the compass that we bring and use during hiking uses a magnet to show us the way we need to go. Recycling centers use magnets to help sort steel objects, such as tin cans, from other recyclables the magnet won't help pick out the soda cans, however, because aluminum isn't magnetic magnets can also be found inside computers, doorbells and soda machines.
