What part of a bar magnet has the strongest force?
The highest concentration of magnetic lines of force is at the poles of the magnet. It's that simple. Here's why. The lines of force are all "bundled together" inside the magnet, and run its length to emerge at one pole. Then the lines of force spread out to "go around" or "surround" the magnet to reach "around" to go back to the other pole. Then they concentrate at that other pole to return to the inside of the body of the magnet. Use the link to get more information and see a diagram.On the Sun, the magnetic fields that create the prominences may be the strongest magnetic fields. On Earth, I'd guess that those used in MRI machines would be right up there, but the fields used to steer particles in the hadron collider may be worth a check as well. I have no numbers readily available for you.
Can you have a unipolar magnet?
No. No matter how far you divide a magnet down, there will always be two poles: North and South. Well ; there is actually a domain in magnets which divides it into N and S. If the magnet is smaller than that, ie a few nanometers, then you can have unipolar magnets. In fact , such objects have been synthesized.
What is the color of a north magnetic pole by convention?
Magnets do not have colors.Further AnswerLaboratory magnets are often painted to indicate their north poles. Usually, this takes the form of completely painting the 'north' half of the magnet, and leaving the other half unpainted. There is no significance as far the colour itself is concerned, it may be black, red, or any other colour.
Which planet sometimes has its poles pointed almost directly at the Sun?
Uranus always has its poles aimed at the sun.. it is unique in that respect (so far)
Why does a broken magnet remain a magnet?
It is so far experimentally impossible to separate the North Pole from the South Pole. Even if you cut the magnet into little pieces, it'll still remain a magnet because there will still be a North pole and a South Pole

Which has more magnetism north or south?
As far as I know, the north and south poles of a magnet are equal in strength, because the net magnetic charge of a magnet must be zero (unless monopoles exist).
Can you have a unipolar magnet?
No. No matter how far you divide a magnet down, there will always be two poles: North and South. Well ; there is actually a domain in magnets which divides it into N and S. If the magnet is smaller than that, ie a few nanometers, then you can have unipolar magnets. In fact , such objects have been synthesized.
What do the poles have to do with magnetism?
Every magnet has a north pole, and a south pole. Unlike electric charges, these can NOT be separated. If you cut a magnet into two smaller pieces, each one will still have a north pole and a south pole. Some theories predict that there should be "magnetic monopole" (isolated poles, that is), but so far, none have been found.
Are bar magnets stronger than horseshoe magnets?
There are some variables like what the magnet is made of and how it was initially magnetized. If a bar magnet is bent into a horseshoe shape to make a horseshoe magnet, the magnetic field will be more dense (stronger) across the gap of the horseshoe magnet than it would have been anywhere around the bar magnet from which it was made. And since magnets are strongest at their poles, horseshoe magnets can use both their poles at once while bar magnets can only use one pole at a time.
How many magnetic poles do the pieces have when you break a magnet in half?
The best way to describe this would be to think of a magnet as a series of legos.Imagine you have a stick of legos (those obnoxious 2 by 2 squares that can't be used for anything) stacked ten high.No matter how many times, or where, you break the Lego stick, you still end up with one end having bumps and the other having a gaping hole.The same is true for a magnet: at the smallest level, a magnet is a dipole, or a "particle", if you will, with one north side and one south side. Dipole stack on each other like legos in this metaphor we're using in such a way that, no matter where you break the magnet, you still have a dipole on the top pointing north and a dipole on the bottom pointing south.Now, there is a hypothetical concept known as a "monopole" (think of a magnet that's ONLY north or ONLY south, like thinking of a Lego brick with ONLY bumps or ONLY holes), but we've never seen one, and physicists doubt they exist.
How are electric charges different then the poles on a magnet?
One important difference is that electric charges can be separated. A magnet ALWAYS has a north pole and a south pole, which you can't separate. If you cut a magnet in twain, you'll get two magnets, each with a north and a south pole. Some modern theories propose the possibility of magnetic monopoles, but so far, in practice, these have not been discovered.
How do you levitate a substance using earths magnetic field?
You can't make a magnet with only one pole. Every magnet, whether natural or electro- , has two opposite poles. One pole is attracted to Earth's north magnetic pole and repelled by Earth's south magnetic pole. The other one is attracted to Earth's south magnetic pole and repelled by Earth's north magnetic pole. For the same reason, there's no such thing as "repel Earth's magnetic field" because Earth itself is a giant magnet, and also has two poles. One of them attracts one end of any magnet, and the other one repels one end of any magnet. Make any electromagnet you like, and figure out a way to hang it up and let it turn freely. It'll line up with its ends pointing to the Earth's north and south magnetic poles.
Which is the distance between a magnet and a paperclip?
Unfortunately this question needs more detail to answer. Are you asking about how far apart a magnet and a paperclip are if they're touching (# of atoms), or how far apart the magnet at my house is from the paperclip in china, or how far apart a magnet has to be from a paperclip before it starts to create a pull (even this would need more details, what size of magnet, what strength, what size of paperclip)?
What happens when you break a magnet?
As you break a magnet, the remnant (broken piece) shall still remain a magnet with the same properties and poles. However, there is only so far a magnet can be broken. Visualize a magnet. Now imagine to have a knife that would keep cutting the magnet into half. It will reach a point that cutting the 'magnet' further would yield into a particle with no magnetic charge whatsoever. This is called a magnetic domain. Cutting a magnetic domain further would yield into a charge-less particle as it would be obviously incorrect to state that an atom of a magnetized steel bar would still remain a magnet.

How can you make a magnet lose it magnetic power?
Methods to demagnetize a magnetThere are several ways to demagnetize a magnet: high temperature, AC magnetic fields, mechanical shocks, and physical distortion. If we heat a magnetic material above its "Curie Temperature," its magnetism vanishes entirely. When the magnet cools down again, all the microscopic magnetic domains will point in circles, so the magnet will have zero overall field. Neodymium magnets have a low Curie Temp., so they are more sensitive to overheating than other types of magnet.If we expose a magnet to the field from a strong electromagnet, the electromagnet will magnetize the magnet perhaps in a different polarity. But if we instead use an AC electromagnet, then move it away from the magnet, the magnet's polarity will flip back and forth, becoming weaker and weaker. The magnet will end up demagnetized. This is called "Degaussing."Steel magnets are sensitive to mechanical shocks, and you can weaken a steel magnet by striking it with a hammer. Other magnetic materials are far less sensitive to hammering.We can also demagnetize a magnet by forcing its poles together. For example, if we bend a horseshoe magnet so it forms a complete circle, its field will become a circle entirely inside the magnet, and it will have no poles or attraction. Or, if we grind a magnet up into small pieces, the pieces will align so the north pole of one fragment will be against the south pole of another, and the outside field will be small or zero.
