Electromagnetism – conceptually what is the relationship between electricity and magnetism (and by extension voltage etc)
In: 7
* Charges exert forces on other charges via electric fields.
* Moving charges exert forces on other moving charges via magnetic fields.
* Changing electric fields induce magnetic fields and vice versa.
* You can create self-propagating electric and magnetic fields which move outwards at the speed of light (in a vacuum). This is fundamentally what light is.
