Is aluminum powder magnetic?
Most matter will exhibit some magnetic attraction when under high enough magnetic fields. But under normal circumstances aluminum isn’t visibly magnetic. This is easily tested by putting a very strong neodymium magnet near aluminum can. They both just sort of site there.

Is thermite in Etch A Sketches?
Aluminum powder is definitely an ingredient in thermite. Walt and Jesse could have easily purchased the powder in larger supply had they just gone to a hardware store, since our calculations suggest they’d need close to 200 etch-a-sketches to fill the baggie in the show.
Can you fix an Etch A Sketch?
3 Answers. An Etch-A-Sketch is a simple machine where the knobs end up moving a string from side to side and another from top to bottom. If the strings stretch or for any reason slip, you will get the behavior that you describe. Other than opening up the unit and replacing the string, there is not much that can be done …

Why does a magnet attract iron but not Aluminium?
Ferromagnetic substance like iron requires no external magnetic field to maintain the magnetization . Like paramagnetic material ferromagnetism is also due to spins of unpaired electrons. Now, aluminum is paramagnetic ,but iron is ferromagnetic. The difference is the interaction between nearby dipoles.
