Part 1.
There are many different types of ways to measure the strength of a magnet. In this experiment, we shall be using ferrofluid as a measuring tool to determine the strength of three different types of magnets. these are regular vinyl magnets. these are ceramic or ferrite magnets. And these are neodymium magnets, a type of rare earth magnet. . This is ferrofluid. It is a magnetic liquid.Magnetic particles are put into the fluid to give it it's magnetic properties.  The ferrofluid will be use to test the strength of these magnets because the stronger the magnet, the stronger the ferrofluid will be attracted to it. the hypothesis is that the neodymium magnetw will be the strongest seeing as how they are rare earth magnetw. Now for the experiment itself. we took the ferrofluid and put it into a petri dish. then we took the magnets, and put them near the petri dish, and we saw their reactions. To best analyze these results, the ferrofluid was extracted off each of these magnets, and from wherever the ferrofluid ended up, to be able to analyze and measure how much ferrofluid was attracted to each magnet.
Part 2.
Due to the fact that the vinyl magnets had little to no effect on the ferrofluid, its result would be 0. The ceramic magnets, had some effect on the ferrofluid, and drew all the ferrofluid that it attracted to the top. It was scraped off the top of the petri dish, and put into the graduated cylinder. The results for that one came out to be 0.6 milliliters. for the neodymium magnet, all the ferrofluid that it attracted came out of the petri dish and on to the magnets. so to analyze the results for these magnets, all the ferrofluid was scarped off the neodymium magnets and put into the other graduated cylinder. There was one problem with analyzing the results of all these magnets. The ferrofluid was too dark a fluid to actually see the numbers on the graduated cylinders. But since this brand of ferrofluid was mineral oil based, corn starch and light fluid were used as a solvent, which dissolved it, and made it easier to measure. and from all these results, we can conclude that the hypothesis was correct.The neodymium was indeed the strongest magnet, and would therefore be attracted to the ferrofluid the most, due to the fact that it is a rare earth magnet.
