I've been trying to think of a new science experiment. I want it to be spectacular. I don't know if it will work though. Can you do some checking of my work?
The plan is to get a string magnet and accelerate it with the help of a spring to a few hundred meters per second, then have it pass through a magnesium ring.
The magnet needs to impart enough energy into.the magnesium ring that it heats up to.The.point of ignition.
Can this work? Can the spring get the magnet going fast enough to induce enough heat in the ring to get it hot enough to.combust?
I can't buy the means to get the magnet going supersonic speed. I do think I can get maybe 200m/s which is just twice as fast as a paint ball or airsoft slug.
I think the magnesium will.ignite from the voltage induced in it according to faradays law.
IF the magnesium ignites it would produce the bright blue flame would it not? i remember it from high school chemistry, you should be careful of that.
Also Magnesium is not magnetic, where would the energy come form that is igniting the Mg
The point of an experiment is resolve cognitive dissonance. That is to test a theory.
We already know that if a magnetic flux [math]\Phi(t)[/math] changes quickly with time, it will induce enough current to heat and ignite the Mg ring in the presence of oxygen.
Which means, in theory, if the spring and magnet were strong enough, it would heat up the ring to a burning point. If it burns the ring, everything went according to your theory.
But you're experiment might not do that, and you're left with the conclusion that your magnet was not strong enough or your ring was too thick or there was to much air resistance. But non of these conclusion falsify your theory, so this experiment is useless.
>Because this "experiment" is stupid and pointless. Do it yourself, no one else cares.
An order of magnitude calc just takes a few minutes. You can't invest 5 minutes in this because of internet troll reasons?

Read the op I'm asking for for someone to.check my work. I've done the calculation myself. I just want a second.set of eyes before I go and order materials.
What's with the incessant trolling? I'd imagine someone with sincere interest in science could.just do some math and come up with a simple answer if it will.work.or not.
