You’re probably familiar with the basics of magnets already: They have a north pole and a south pole. Two of the same pole will repel each other, while opposites attract. Only certain materials, especially those that contain iron, can be magnets. And there’s a magnetic field around Earth, which is why you can use a compass to figure out which way is north. In this episode of Crash Course Physics, Shini takes us into the world of magnetism!

8 – What is the key difference between them?
9 – What does the reproduction of south and north pole in magnets divided in half?
10 – What is the measure unit for magnetic fields? How many Newton per Ampere-meter does it correspond to?
11 – What else did prof. Oersted discover during that lecture? How?
12 – What was prof. Oersted's third discovery after a few more months?
13 – a) How can the direction of electric current and that one of magnetic field be remembered? b) How many right-hand rules are there? c) What does the FIRST
right-hand rule say? d) What is the consequence?
14 – a) Why is the …….
… right-hand rule useful? b) How can you figure the
direction of the magnetic field out? c) What does the thumb direction show? c) How is the strength of the magnetic force represented? d) Explain the equation.
thank you
comes in handy indeed haha
This video was so well constructed, now I have to find all of your other videos because you've explained this so well. Time to learn! Thank you!
Can anyone tell me in which class this is taught other than India 🙂
What if our earth magnetic force somehow just disappears or cancelled out?
Thank you so much for this! Very helpful and informative.
Y when i search when was electricity invented it says 1879 so had did he use electricity in 1820
NIKOLA TESLA WAS A FAMOUS SERBIAN-AMERICAN SCIENTIST born in Austrian empire, modern-day Croatia.
try taking notes without pausing the video… 😐
DEN LIKE SI ESTÁN VIENDO ESTE VÍDEO SOLO POR LA ESCUELA
Don't know about US prices but on Amazon in UK you can get magnets and iron filings for under £10, so if you're out of school 'cause of Covid, got a bit of pocket money and you like learning with practical experiments take a look
she's so pretty
I feel stupid after having watched that.
7:45 damn it, a man can't masturbate in peace these days
Like magnetism … hate people who drop half the alphabet and twist the other half when speak
Great video… Entertaining and informative. 🌞
I'm dumb now I'm even dumber
You're talking way to fast. You are NOT a good teacher.
Sorry if I have missed something here but at 6:01 can someone please explain why the magnetic field is not uniform and is elongated on the side of Earth that is facing away from our Sun?
just put the speed to .75 its normal talking
POV: you're watching this because of corona….
your teacher sent this to you with worksheets
you're procrastinating, instead of watching the video ,you're reading the comments
the comments aren't funny
you're bored now.
love the lego millenium falcon in the background
tip to understand: change playback speed to 0.9x
Naughty, but Nice 3:46 Aaah – 3rd base type of juvenile humour! ./.
Slow down!!! But thanks for the help
what’s da answer 4 # 3 😔😔😔😔😔😔😔😔😔😔😔
alright who has the answer for number one
I blinked once and now I’m lost
Wow…
You can clearly see that she is looking at like something she can read off of behind the camera.
Thank you beautiful human beings for the knowledge.
indian person alert
india
Wh…what?
You sneeze you miss half of the video
"No, you dunce, she means magnetism!"
"… magnets are cool, too"
ey yo, my teacher ordered me to watch this during quarentine check
I search magnetism, enter this video and the first thing that pops up is an advertisement about being magnetic to people.
She's talking so fast! Good info however.
her eyebrows said 📈📉 📈📉
