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?

So what are you trying to do? The point of an experiment is to test a hypothesis.
>>
>>7781133

My hypothesis is that the ring will explode with material I can easily and cheaply procure.
>>
Why do you think the magnesium will ignite from a supersonic magnet passing through it?
>>
>>7781148

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.
>>
Maybe an electromagnet would be better.
>>
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
>>
>>7781189

It's faradays law.

V=-d/dt(flux)

The ring material doesn't need to be magnetic. Otherwise no inductor or transformer would work.since they are made.If copper wire.
>>
>>7781139
Ok so what do we gain from this experiment that we don't already know?
>>
What are your variables?Or are you just seeing if one size of Mg ring will ignite after one sized/power of magnet is used.
>>

>>7781139
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.
>>
So no one here can do a simple order of magnitude calculation?

I just get pages of troll replies and not one number?
>>
>>7781314

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?

flawless reasoning

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.
