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

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