... A uniform electric force and field can be made by placing two large conducting plates parallel to each other. One is charged positively and the other negatively. The electric field between the plates is constant except for the edges of the plates. Remember the equation: E=F/q. If E is fixed for a ch ...

Topic 6.2 Electric Force and Field
... Law of Conservation of Charge • When charging objects by friction, charge is not created but rather redistributed on the two surfaces. This can be stated according to the Law of Conservation of Electric Charge that states that in a closed system, the amount of charge is constant. • If you examine t ...

ELECTROMAGNETS
... Give each student a variety iron nails and other shaped metal objects and 20" copper wire, and tell them make their own electromagnet. The aim is to make the strongest electromagnet that will hold the most paper clips. When the participants have finished their design of an electromagnet, have them b ...

TOPIC 4.2: ELECTRIC FIELDS
... Students define the electric field strength, E, as a force per unit charge (in N/C). The electric force is given by Fe = qE, and lines of force are used to draw the field. The field between two parallel plates is described. Students examine problems involving both the gravitational and electric forc ...

History of electromagnetic theory
For a chronological guide to this subject, see Timeline of electromagnetic theory.The history of electromagnetic theory begins with ancient measures to deal with atmospheric electricity, in particular lightning. People then had little understanding of electricity, and were unable to scientifically explain the phenomena. In the 19th century there was a unification of the history of electric theory with the history of magnetic theory. It became clear that electricity should be treated jointly with magnetism, because wherever electricity is in motion, magnetism is also present. Magnetism was not fully explained until the idea of magnetic induction was developed. Electricity was not fully explained until the idea of electric charge was developed.
