this link was so helpful!thank you very much!

Hello Everybody, i would like to ask if anyone around here has any prior knowledge regarding magnetic nanoparticles and their properties and could provide me with a useful link so that i can search deeper and learn more. What i would like mostly to know is if they can emit a magnetic field...

i have looked into this site before too!their diameter is too big! So no electromagnets can work for it!

Hello everyone, i am seeking for an ultra strong cylinder neodymium N52 magnet or something stronger if it exists(i know N52 is the strongest ^^) with these dimensions : length : 2-3cm diameter : 0.7 mm I have searched and talked with many companies but either they require...

Thank you very much! an aluminum spray did the work :)!

I want a cheap coating method in order to coat a plastic object (i don't know what exactly, anything thin like a wire) and make it visible in an xray machine so that i can experiment with x ray techniques, like the one dentists use.

i want to detect object which are not visible in x ray by using x ray. In order to do that i am searching for a cheap and fast solution to coat these objets , with something visible in x ray. I would like to ask if the gold and plat spray paints can be visible in x ray. Or if there is another...

thank you very much!can you suggest any link to find a spray suitable?

Hello fellows, i would like to ask if you might know any spray with metal elements which can be visible in X-rays. I want to use it as coating in objects. Does any common gold or plat spray be used? Thank you!

actually i found out that the magnetic moment of a wire with length L is M , where M = m*L. m is the magnetic pole strength. how can i calculate the value m for a iron or steel wire?

Hello! Thanx for your reply! I have a magnitize/demagnitize device and i want to magnetize a wire! How do i find the magnetization? Is it the magnetization of the device?

Hello all, i would like to ask which is the magnetic moment of a steel and a iron wire with a length of 10,20 or 30cm! Is there any equation from which the magnetic moment can be derived? Thanks in advance :)!

xmmm ok thanx!it is just that i read somewhere that magnetic moment goes to zero if i unite 2 magnets in their different poles and that confused me a bit!

What Changes If i Place two magnets together?? Hello everybody, i wanted to ask what changes when i unite two magnets ?? except from the dimensions does magnetic moment, Br change? Thanx in advance!

ok!thanx for your time!i will come back when i manage to make it work :)!
