The Importance of Electromagnetism

The overarching force is called electromagnetism and the aspect of that force that we're going to look at in this episode is electricity. An electric charge or just electric charge is simply a physical property of matter that causes it to experience a force when it's near some other electrically charged matter. Originally these were thought to be completely separate forces, but in the 19th century it was found that changing electric fields can give rise to magnetic fields.
