try some rare earth magnets. they are cheep, strong, then you can put them on the outside of the container and its color or shape won't affect your results.
A transferring ion would have an magnetic field. despite the undeniable fact that, because the price on the ion is so small, the field itself is likewise just about immeasurably small. as to no matter if nonmoving atoms generate magnetic fields - atoms do not, because they continually have contra-rotating electrons. Ions do, yet back - it really is pathetically small.
Yes. Or build a solenoid and power it from a suitable source. It depends on what the hypothesis is that you're trying to test. The effect of static magnetic fields? The effect of time-varying fields (use AC power - ah, but perhaps the frequency has an influence?) First build a testable hypothesis.
Ceramic holds heat better and doesn't damage the hair as much.
Ceramic flat irons are powerful tools for making hair perfectly straight and smooth. Ceramic tends to be much better than other flat iron surfaces, such as gold-plated metal or chrome. Ceramic is the preferred material for flat irons because its surface does not tug, catch, or pull on hair. Therefore, there is less breakage and hair damage than with other types of flat iron surfaces. Ceramic flat irons are also desirable because their surface area can become uniformly hot. Other metal flat irons may have some surfaces that heat up faster than others. The even, high heat that is provided by ceramic flat irons allows for hair that is sleek and stick-straight in appearance. Even permed or naturally curly hair can be made completely straight with the right ceramic flat iron.
