Suppose that someone argues that when a bar of iron is magnetized, all the north poles go to one end and all the south poles go to the other end. How could you disprove the suggestion?

of iron is a collection of domains in which fictitious small
magnets are randomly oriented. If we applied mmf then all the that
small magnets in domains aligned along the magnetic field applied
by mmf.
All the confusion will be cleared by posted picture.
In picture 1, all the fictitious small magnets are randomly oriented as "in any material electrons are randomly in motion". When we applied an external magnetic field or mmf, all magnets in the domain are oriented along the magnetic field.
They behave like series of magnets, as shown in figure 3.
Corner most magnets left-hand side having a south pole and right-hand side will be north pole. All others will behave like cancel out magnetic fields.

You have one magnet with the north and south poles labeled. How can you use this magnet to identify the north and south poles of other magnets?
1. The stack of magnets works as one big bar magnet. Do the poles change when you divide the magnet into pieces? 2. In step 3 of the experiment, do both sides of the magnet attract the metal surface? Explain how a single magnet can repel the rest of the stack, but still stick to the other surface. 3. How does the magnet attract something that is originally non?magnetic? 1.

You make a seesaw by placing a 50-g magnet (whose poles' faces
are 2-cm-by-2-cm squares) at one end of a 50-cm-longruler and a
small 50-g metal object at the other end and balancing the whole
setup by placing a pencil directly under the middle of the ruler.
You know that the magnet is horizontally magnetized, but you don't
know which face is north and which face is south. When you place a
horizontal wire close to the pole of the...
could someone show me step by step for this
such as how to go about/get dy/dx etc.
i know the final answer is 4 pi ^2 ab , but I can't seem to get
there as no one shows the steps
when I attempt it I end up with 2pi instead of the correct
4pi

Could someone check my answers, please? 1. Suppose that a species of fish has split into two populations in a lake: one on the eastern side and one on the western side. How could you determine whether the two populations constitute different species? A. Examine the populations for morphological, color, or other physical differences. B. Examine the populations for different genetic markers and allele frequencies. C. Attempt to breed members from the two populations in captivity. D. Introduce members from...
Bar Stool Economics Suppose that every day, ten men go out for beer and the bill for all ten comes to $100. If they paid their bill the way we pay our taxes, it would go something like this: The first four men (the poorest) would pay nothing. The fifth would pay $1. The sixth would pay $3. The seventh would pay $7. The eighth would pay $12. The ninth would pay $18. The tenth man (the richest) would pay...

I HOPE TO SEE MY PILOT FACE TO FACE WHEN I HAVE CROSSED THE BAR England's great poet laureate was nearing the end of life. His time was running out, and he knew it. But he knew it with- out fear, and without regret. For to him death was not an end but a beginning; death was not the final curtain but merely a change of scene, the transition to another and perhaps an infinitely better life. Alfred Tennyson believed...
Could you show how this problem is worked, when
according to the last sentence of the paragraph ( Assume the

In one instance there's specific borrowing and in
another there is non- specific. I want to see the difference and
