Thank you here's Your shmoop du jour brought to you

00:05

by magnetism We've been told that we have a magnetic

00:08

personality that people are really drawn to us now Which

00:12

of the following best described magnetic permeability and hear the

00:16

potential answers Acceptability All right if something's permeable what does

00:23

that mean Well if we're not speaking in physics sees

00:26

a substance is permeable if it allows air or water

00:30

to pass through it A screen door is permeable A

00:33

wooden door so much but magnetic permeability is a measure

00:37

of materials Ability to sustain a magnetic field material can

00:42

be highly magnetically permeable like iron Or it can have

00:45

a low magnetic permeability like a piece of wood Wood

00:49

doesn't carry a magnetic single right Why is that Well

00:52

after all we wouldn't consider a block of iron to

00:55

be very impermeable Permeability in this sense doesn't refer to

00:59

air or water going through a material It refers to

01:02

a magnetic field going through it instead Let's Think of

01:05

iron again If we bring a magnet near a piece

01:08

of iron the magnetic field will act on it In

01:11

fact the magnetic field can even turn a normal piece

01:13

Of iron into a magnet So if the material is

01:16

highly magnetically permeable than a magnetic field is able to

01:20

act on it and flow through it so the correct

01:23

answer is c on objects ability to sustain a magnetic

01:26

field There we go way Think we've got that figured

01:28

out now which makes sense Our mom does say how

01:31

smart we are It looks like she's right again Thanks 00:01:34.429 --> [endTime] mom
