Magnet

Did anyone know that if you hang an iron rod from a string after a few days it will become magnetized, this is how natural magnets are formed when iron ore is lying north to south in the ground...

If theirs no files or disks, then theirs no string!

After looking at the solution... I have one question..

If there is NOTHING In the room but the iron rods, where do the pieces of string come from? :huh:

Can't you hold each iron rod close to your watch, one at a time, and see which affects it?

The bane of my existence has been small, powerful magnets. Why? Because they require a lot of control to work with. Why? Because without any control, they will pull themselves at high speeds towards each other or toward attractive objects, as is the want of magnets. Why is this a problem? Because they are extremely brittle, and they break quite easily when subjected to severe impact, the kind of impact that they can impart on themselves given their strong attractive force and small inertia.

Now, you can make a magnet out of an iron rod or other stronger material, so this solution won't work if that is the case. I believe the best solution remains the "T" formation test which plays on the fact that all magnets are dipoles, but here's mine:

Depending on the material from which the magnet is made, it's likely that the magnet will be far more brittle than the iron rod, and thus will break completely upon impact, or at least flake. So, bang the rods together. Whichever one breaks is probably your magnet. Depending on the size and shape of the magnet, you could potentially break it with your bare hands. The iron rod would bend long before it breaks.

I've loved magnets since I was a kid. See which rod's end will stick to the midpoint of the other rod. If an end of rod A sticks to the midpoint of rod B, then rod A is a magnet and rod B is not. Think about it, or try it.

accually hanging the rods ona string would not help because they will both point in a directin how are you sopposed to know which direction is north? so the obvious answer would be to take both poles... and with the pole in the right hand touch the top of the pole in the left hand with the top of the pole in the right hand... it will either stick or repel... not with the top of the pole in the right hand touch the botton of the pole in the left hand... if the magnet is in the right hand it will do the same as b4 either stick or repel... but if it in your left hand it will do the oposite

That solution wouldn't work because it would attract both times no matter which hand the magnet was in

when i read this, i literally jumped out of the computer chair because it is so easy....

You rub one stick with the other, and the one that becomes a magnet isn't the magnet...you can actually do this, im not making this up. I forgot what it is called, but it actually does work

This can be solved with only these 2 items.

I recall learning in elementary that you can magnetize a metal rod (rod B) by running a magnet (rod A) over it several times in the same direction. While, if you run a single point of a metal bar (B) over a magnet (A), the entire metal bar (B) will not become magnetized. By attempting to magnetize with the other, you could tell which one was the magnet (A), by simply attempting to get the polls to push away after trying to use one to magnetize the other. If you find that neither of the ends of the rod that had been ran over the other repels one end of the other rod, then you will know that the rod that was ran over the other was not a magnet.

The unmagnetized pole will stick to both sides of the magnet, it will never get repelled. this way would work if there were two magnets and three poles, but there aren't and that would be too easy.

I thought about this all day, and after coming up with a solution I was surprised to come home and read that the provided solution actually seemed much more complicated than the one I came up with, it's usually the other way around.

Alternate solution: Break one or both rods and the one who's pieces attract or repel eachother is your magnet.

that seems a whole lot easier and it would work!

yup.

Thankyou Timm, as I read the question this is exactly what I thought of as well. Assuming what you say is true about magnetising an iron rod (which I also learned), this is logically sound.

Well you rub the iron rods together so iron dust comes of. then you take this iron rod and you trom it over one of the rods.

the rod which is magnetic will make lines from north to south in the iron dust and the non magnetic rod will not

hold it up to my face and see if it sticks. you see i have a plate in my jaw. :P it works with fridge magnets it should work with a regular magnet. in my case if it sticks it's a positive magnet.

Pick up one of the rods, and hold it over the other one, without the two touching eachother. If the one that you picked up is the magnet, it will draw the other one up, if it's the one still on the floor, it will draw the one you're holding toward the floor. (I think....)

I think it wud work.Center of the magnet is nutral, so when we touch a rod to the center of other rod,if it sticks with it then the lying rod is iron rod ,otrherwise it is magnet rod.

this isn't quite a logic puzzle. magnetic rods have maximum attraction toward the ends and are neutral in the mid point. so, take the two rods and form a T. if the T stays, then the leg of the T is the magnet and the top of the metal. If the T doesn't stay, then the leg of the T is the metal and the top of the magnet.

Hopefully you're wearing pants, and theres a magnet, so you can just find out by putting your pants up to the pole lmfao

Magnets do not react with room temperature.

The colder one is the metal.

Isnt pitch affected by magnetism? Also im pretty sure licking a magnet is diffrent than licking a metal.
