... 2. Most TV’s and computer monitors use what is called an electromagnet to guide electrons to the screen. An electromagnet is created from coiled wire. It acts similar to a switch turning on and off its magnetism by current. When a current is passing through the coil, it becomes magnetized. When ther ...

Ampere`s law of force
... In Coulomb’s law, it was useful to introduce the concept of an electric field to describe the interaction between the charges. In Ampere’s law, we can define an appropriate field that may be regarded as the means by which currents exert force on each other. ...

... The magnetic field surrounding the earth is produced by convection currents in the outer core of the earth in combination with the rotation of the earth. The shape of the field, however, is very much like that of a bar magnet, and so one can imagine a bar magnet in the earth producing the field. Bel ...
