No, no one ever said they are electromagnet.
You didn't say it.
I didn't say it.
What I said was that you can take a regular magnet and change it's polarity by running an electrical current through it.
Learn to read.



And using your high school edumacation in all the wrong ways.

You need to go back to school.
You can change the polarity of a magnet by slamming it very hard. That is not what is happening when you place your cover on an iPad.




I am merely explaining to you the various ways that polarity can be changed.... and ruling them out.
Of course, you could debate this with Apple engineers... I'm sure they would roll their eyes and delete the email.





How you can equate placing your cover on your iPad with banging a magnet hard enough to reverse its polarity is an exercise in stupidity.


Oh yeah....SSDs don't have magnets.. blah blah blah...
You need to do more research.


Now you can start a thread on how to manage the nuclear crisis in Japan.

The World According to Carp.

LOL - I like you big guy, just sometimes your turn a bit condescending = which makes me a bit more defensive

You need to go back to school. <-- Oh really
You can change the polarity of a magnet by slamming it very hard. That is not what is happening when you place your cover on an iPad.

Every time you attach the cover, look at the TV commercials you are slamming (tiny) magnets together. I can see it.

Like I said Apple must feel the reversing is very remote.

Oh yeah....SSDs don't have magnets.. blah blah blah...

I never said that - are you reading or skimming ? ?
It was Michael who mentioned that SSD'a are magnetic drives - hence placing magnets inside is not a good idea, therefore metal strips instead.

Of course, you could debate this with Apple engineers... I'm sure they would roll their eyes and delete the email.

And your so sure of that
Besides, there is only one way to place the cover on to begin with, soooo kinda a moot point.

I’m not sure why nobody has linked to this simple video that clears everything up. Maybe because it has a gratuitous F-word. Sorry about that. Still, very informative about magnets!

OMG.. that's so funny it's hilarious. You just proved why they came up with the saying...If that isn't the pot calling the kettle black.

You should read your own posts. You are the king of condescension.
It's what gets my ire worked up.
Any condescension from me comes after tirelessly slamming my head up against a rock of ignorance and beginning to see the rock is bigger than I thought it could ever possibly be....
You can't even stay on topic.



I think that point has been made already....

This discussion was about reversing polarity. Small clicks with magnets (tiny or big) does not reverse polarity.



Noooo.... I said...You can change the polarity of a magnet by slamming it very hard.
Bzzzzt! Take another lap.

If smalll clicks.. or slamming as you call it.. reversed polarity (either a small amount or any at all) then all the MagSafe adapters would be popping out by now and no one would be able to power their laptops.



Nuff said...


My apologies about the SSD comment... there is so much erroneous info in this thread that I just assumed that one was also yours.

Thanks

It does not load - Humm
Will check back later.

I am done talking about this subject, obviously you don't understand.

Sorta like that TV commercial (What makes Peter, Peter) I write one thing you read something else

LOL.. I watched that last night while looking up the videos about ferro fluids.
It's an internet meme...
Also, asking Mormons how do magnets work.

Going to make some ferrofluid of my own when I have some time.

I understand fine.

No one is slamming their iPad covers hard enough to reverse the polarity of the iPad magnets.

You made a mistake and don't want to admit it. That's ok.. I expect that from you.

I made no mistake.

We are not talking about giant Bar Magnets - just little tiny ones that Apple installed, so you don't need to bang them as hard as the big Bars.

Anyway, like I said Apple feels that is a non issue.

LOL...
You are confusing yourself again. You originally said Apple.. well.. here.. a refresher on what you said...




Now that you have seen the tear down that was posted and seen that YOU WERE WRONG... you change your story to be polarised with what Apple did.

Hi-frikkin-larious.



I think you are confused about what you remember in high school... or grade school.. whatever.

The lesson as I remember is that you would bang a magnet to demagnetize it. The poles would be out of alignment with each other.

THEN.. you would rub a good magnet or a bar of iron against the demagnetized magnet... realigning the poles. Either with the same polarity or reversed.. depending on which side you chose to restore.

Now no one is going to bang the magnets and then take the unit apart and rub them from the other side so that the poles are reversed.

In addition.... if you bang magnets on something non magnetized like a desk or the floor.. then the domains become misaligned and it "loses" it's magnetism. As I just told you... rubbing them on a bar of iron or another magnet will realign the domains (poles) and restructure the magnet so that it is functional magnet again.
Now...... are you ready for this Carp?
If you are banging a magnet against another magnet... any harm is negated by the fact that the other magnet is constantly realigning the domains.. actually... they are both constantly realigning themselves. So it's probably, as near as I know, impossible to destroy the magnetism that way.

You can heat up a magnet, run electricity through it, degauss it, and so on..you can demagnetize it by rubbing it against a stronger magnet with an opposite field.... but it will still have some magnetism because its magnetized.. that's the physical property of magnets. No matter how misaligned the domains are... you can come back to the "banged" magnet 200 years from now and restore it's functionality.

Bzzzt...
Take yet another lap and see me after class.
