- [Instructor] The physical force that causes electrically charged particles to interact with each other is called electromagnetic force. And as the name suggests, electromagnetic force includes both electricity and magnetism. Yes, That's electricity, The thing we've been talking about throughout this course, things like voltage and current, as well as magnetism, that mysterious force that makes magnets stick to a refrigerator. And there's an important relationship between electricity and magnetism, because they're really just two different instances of the same electromagnetic phenomenon. When electrical current flows through a wire, it creates a magnetic field around the wire. Now we can't see or feel that magnetic field, but it surrounds the wire in a circular pattern and can interact with other nearby objects. The strength of that magnetic field is directly related to the amount of current through the wire. As…
