Thank you We sneak and here's your shmoop use your

00:05

rock to you by magnetic fields and no magnetic fields

00:08

aren't where magnus grow come up mary magnetism gets a

00:13

brand new bar magnet for christmas Check out these magnetic

00:17

field diagrams which diagram correctly illustrates the magnetic field around

00:22

the bar magnets All right what mary do to get

00:26

on santa's bad side like this if we open a

00:29

present on christmas and it's a bar magnet well someone's

00:32

getting talking too But far magnets are a good way

00:35

to explore magnetic fields because the two holes are obvious

00:38

All magnets have a north and a south pole that

00:41

goes from a tiny atomic magnet to the earth itself

00:45

Anyway the magnetic field that's generated moves in a very

00:47

specific way It's not like a point source radiation going

00:51

out in every direction like in history and it doesn't

00:54

go from south to north like an answer c and

00:58

there aren't two separate magnetic fields going around each half

01:02

of the magnet so d isn't right either Doesn't take

01:05

sherlock holmes figure out that the correct answer is b

01:07

magnetic field lines run from north to south and they

01:11

don't just go around The outside of the magnet field

01:14

runs through the magnet itself Now that we know more

01:18

about magnetic fields we've got to go dig up the

01:20

magnets we planned in the backyard They're starting to attract 00:01:23.67 --> [endTime] robotic birds Tweet
