Physics 165 Chapter 4 Questions with Answers
(100% Correct Answers)
Orbital magnetic moment Answer: The magnetic field that is perpendicular to
the plane of the motion
Spin magnetic moment Answer: The magnetic field is also perpendicular to
motion of spinning
Magnetic field lines have ... and ... .... Answer: North and south poles,
Each little magnet is called Answer: Magnetic dipole or magnetic domain
When magnetic domains align the object it acts like a Answer: Magnet with
north and south poles becoming magnetized
Lines of force is also called Answer: Lines of flux or magnetic field
Force fields created when magnetic dipoles align to create magnet Answer:
Lines of force
The stinger the magnet the more ... .. ...which is greater ... ... Answer: The
more lines of flux, greater flux density
Lines of force flow from _______ to ______ outside of the magnet Answer:
north and south
Lines of force flow from _______ to ______ inside of the magnet Answer:
South to North
Magnetic fields strength is measured in Answer: Gauss and Tesla
3 principle types of magnets Answer: Natural- earth
artificial- compass
electromagnetic- wire wrapped around iron core
, 2
Magnetic laws Answer: 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
Ferromagnetic Answer: Easily magnetized, strongly attracted
Ex: iron
Paramagnetic Answer: Slightly attracted to magnets
Ex: aluminum
Diamagnetic Answer: Weakly repelled by magnets, cannot be artificially
magnetized
Ex: water, lead
Non magnetic Answer: Unaffected when brought to magnetic field
Ex: wood, glass, rubber, plastic
Permeability Answer: The ease which a material can be magnetized
