Maybe you can really capture magnetic fields

We have known for years that many animals can somehow capture magnetic fields. Birds apparently use the Earth's magnetic field to navigate. Dogs find a box that contains a magnet, better than a similar box with a treat. But humans can not visualize magnetic fields without help. Several scientists from California, New Jersey and Japan have conducted experiments that seem to show that people's brains change when a magnetic field turns. If the article titled "Transduction of the geomagnetic field as proof of the activity of alpha-bands in the human brain" is a little for you, the video from Veritasium (below) might be much easier to analyze than the paper.

Recording a magnetic field in an isolated chamber is also different in that it is recorded on the sidewalk and used to navigate.

However, there is evidence that human cultures have been shaped by this past. In a number of human languages, there are no specific works for things like front and back. Instead, cardinal directions such as north and south are used.

If you really want to capture magnetic fields, it's best to insert a magnet into your finger. Then you do not really need to use your finger. [194559008]
