1. Orbital magnetic moment: The magnetic field that is perpendicular to the plane of the motion
2. Spin magnetic moment: The magnetic field is also perpendicular to motion of spinning
3. Magnetic field lines have ... and ... ....: North and south poles,
4. Each little magnet is called: Magnetic dipole or magnetic domain
5. When magnetic domains align the object it acts like a: Magnet with north and south poles
becoming magnetized
6. Lines of force is also called: Lines of flux or magnetic field
7. Force fields created when magnetic dipoles align to create magnet: Lines of force
8. The stinger the magnet the more ... .. ...which is greater ... ...: The more lines of flux,
greater flux density
9. Lines of force flow from _______ to ______ outside of the magnet: north and south
10. Lines of force flow from _______ to ______ inside of the magnet: South to North
11. Magnetic fields strength is measured in: Gauss and Tesla
12. 3 principle types of magnets: Natural- earth
artificial- compass
electromagnetic- wire wrapped around iron core
13. Magnetic laws: Repulsion attraction- alike repels, unalike attract
Inverse square- force is inversely proportional to distance between 2 magnetic fields
Magnetic poles- all magnetic shave north and south poles
14. Ferromagnetic: Easily magnetized, strongly attracted
Ex: iron
15. Paramagnetic: Slightly attracted to magnets
Ex: aluminum
16. Diamagnetic: Weakly repelled by magnets, cannot be artificially magnetized
Ex: water, lead
17. Non magnetic: Unaffected when brought to magnetic field
Ex: wood, glass, rubber, plastic
18. Permeability: The ease which a material can be magnetized
19. Retentivity: Ability to remain magnetized
20. Magnetic lines of induction: Imaginary magnetic field lines
