1. Electricity and Magnetism
2. Electric Compass’ were used
3.It is a good condictor of electricity electron
4. Not until after Mechanics
5. Magnetic compass
6. (Tape notes in notebook) Some things attract, others repel. All objects fall and move with respect to gravity.
7. Benjamin Franklin
8.A fundamental element of mass
9. Like repel, different attract
10. far apart- hard to tell they are attracting, close together-easy to notice.
11. They both have like currents and likes repel, opposites attract but magnets have poles not charges. They are still positive and negative.
12. In one direction there I am electric field and in another magnetic, they work together
13. Friction at a distance
14. Attraction would change instantaneously
15. Nothing can travel faster than light
16. The field of force
17. It is the field that tells two objects how to interact
18. The earth's mass is so big that it barely moves
19. Action at a distance is every part of the earth pulling at an object.
Whereas a field of force is better because it creates a field for a disturbance to travel through.
20. They are centered around something and the farther away from it the weaker the field.
21. Everything is pulled to the center. The farther from the center the weaker the force.
22. Electric charges in the center
23.
In my notebook
24. Because this is our earth, it surrounds us completely
25. Electric generator, electromagnet, electric motor
26. A generator uses motion to make electricity. A motor uses electricity to
make motion.
27. Moving it, moving a coil, turning an electromagnet on and off
28. Energy, mass, weather, volts, compounds
29. Credit card, electricity
30. He thought that it was this way and used common sense to then propose this idea.
31. Electricity make magnetism and magnetism makes electricity
32. The second synthesis is putting magnetism and electricity together as described in Maxwell's equations.
33. Because
