MRI (magnetism)

MAGNETISM

A field effect associated with

certain types of material said to be

magnetic.

It is related to moving electrons

MAGNETIC DOMAINS

Smallest region of magnetism

ELECTRON CONFIGURATION

Describe where electrons are located

around the nucleus of an atom.

FERRO, PARA, DIAMAGNETISM

three types of magnetism

FERROMAGNETIC

strongest magnets, Easily magnetized and have a magnetic

susceptibility greater than 1. (ALNICO)

SUSCEPTIBILITY

How easily material can be magnetized

PARAMAGNETIC

These materials have a magnetic

susceptibility less than 1 (WEAK)

DIAMAGNETIC

Have negative magnetic

susceptibility and in fact are slightly

repelled by magnets.(UNAFFECTED)

DIAMAGNETIC

WHAT TYPE OF MAGNETIC MATERIAL IS WATER?

DIPOLES

Has two poles, North and South pole.

ATTRACTION/REPULSION

Like magnetic poles repel and

unlike magnetic poles attract.

MAGNETIC INDUCTION

Process of making “nonmagnetic” material into MAGNETIC material

PERMEABILITY

Property that basically allows magnetic lines of force to pass through a material.

ELECTROMAGNET

Creates magnetic field through electricity

SOLENOID

proper name for “ELECTROMAGNET”

GRAVITATIONAL FORCE:

If it is assigned a relative value of 1, the

electric and magnetic forces have a value

of 1037 times its magnitude. INCREASE MASS, INCREASE ATTRACTION

GAUSS’S LAW

-Interaction of magnetic field

-Magnitude is proportional to the

product of the two interacting

magnetic poles
