Ferromagnetic fluid

September 1, 2010 Fascinating chemistry 147 419 21

Ferromagnetic fluid - liquid strongly polarized in the presence of a magnetic field. In other words, when an ordinary magnet approaches this liquid, it begins to make certain movements: it jumps up like a hedgehog, sticks to a magnet, and rises with its hump.

This ferromagnetic fluid is quite simple to do at home.

To do this, we need oil (motor or sunflower or other) and toner (powder) for the laser printer.

All these two ingredients need to be mixed by eye until a thick sour cream.

For the best effect, you can warm in a water bath, stirring for 20-30 minutes.

But note - not every toner for a printer is good to magnetize. Accordingly, you need to take the best.

All! Is it simply not true?

I tried to reproduce. I bought Master’s toner for Samsung ML-1210 / ML-1250 / ML-4500, 85g powder bottles - 45 rubles. [b] Nothing happened. [/ b]
Well, then I found out that for printing in printers they use the so-called "developers" - these are powders of crushed magnet. Particles of powder are balls coated with something else. It is interesting to know the radius of these balls. So the developer is an additional magnetic powder to the toner, it is needed not for all types of printers, but in many. It is sold separately and is magnetic. The toner itself does not have magnetic properties. Some toners may be sold as a mixture of toner powder and developer powder. But, I think that in any case, the best solution would be to buy a developer for toner. I found the cheapest 500 rubles.

From Samsung is not suitable, they have in the cartridges the non-magnetic principle of applying toner to the drum. Best suited for HP or CANON.

We look at Wikipedia in the laser printer section.

“One-component (eg, modern Canon and HP printers) is only a toner without any impurities, the coloring particles of which are magnetic in themselves. Xerox / Samsung / Brother printers use non-magnetic toner with an electrostatic toner system.”

So we take a toner for HP or Canon.
