Electricity
This illustration shows the field between two equally and oppositely charged spheres, mapped out by lines of force.... |
|
Electricity
This illustration represents the field between two equal positive charges; in this case the lines of force do not pass from one to the other, but travel off to an infinate distance.... |
|
Electricity
This illustration shows the lines of force when a positive charge equal to 4 at A, and a negative charge of 1 at B, are used. A being numerically stronger than B, lines starting from A will not fall o... |

Electricity
This illustration shows the field of force due to a charge 1 at A, and a like charge 4 at B.... |
|
Electricity
This illustration shows the field of force between two parallel planes. At the edges its lines of foce curve out. Some pass from the back of one plane to the back of the other.... |
|
Electricity
A is a positively charged conductor and B represents the equal and oppsite charge. When the conductor C is introduced into the field, some of the lines of force are divided, since they cannot exist in... |

Equipotential lines
"When a charge is moved from any point to another point in the same equipotential surface, no work is done upon it. When a charge is moved from one such surface to another, the work done is independen... |

Induction, lines of force
"Lines of force of a charged sphere and a conductor under induction. The negative electrification on the end a of the cylinder indicates that an equal number of lines set out from that end." -Hawkins,... |

Solenoid
"Coil some No. 12 copper wire throuh holes in a board, as shown, and pass a strong current through it. Sprinkle iron filling as before and note the effect. Such a coil of conducting wire, wound so as ... |

Solenoid, with iron bar
"Place a strip of shet iron in the solenoid, as shown...Hotice that most of the lines of force are gathered into the iron and issue from its ends. Notice that the lines curve outward and tend to retur... |
