Shark magnetic sensory system from wikipedia.

If we did not have sensitive nerves embedded all over our skin, we would not be able to feel the presence of wind. Similarly, if we don’t have electromagnetic sensors like a shark we cannot sense the presence of magnetic forces. This is an example of electromagnetic pulses that come from the subway system in Japan. This is just one example of simple way you can visualize the invisible forces of the world around you. Think wind!
