Relaxation oscillator Noob need education

Don´t laught please need some help about my project what i basically want is a solenoid "electromagnet" That switch its magnetic flux in a Oscillation fashion. Much like a speaker my solenoid is about 1.5 ohm. And to get the oscillation i research about relaxation oscillator and transistor oscillator but i went for the Rel for the of easy build. But i am very noob and i cant get it to work. The pic below show schematic and how i assemble it

Probably i am so noob that my theory is not valid. I want to have the output voltage the same as i take in in order to get stronger or softer magnetic field but i only get 0.04 mv at the output i have an pot to regulate the freq the voltage do increase or decrease in the output some but do not oscillate i think.. i thing i destroyed the ic or i connected it wrong. or it is the wrong circuit all together? hope i have explained my self clear sorry otherwise!

 

Hello duke yea i have probably killed the IC my calculation with falstad simulation a 1uf cap and a 10k pot willbe around 45hz.. Yea i have seen i some circuit they usa a transistor at the end. But i have seen some use speakers to so i just tested..

so what is best way to go about this?

the cap in the pic is a 10uf just tested if the cap was dead

 

What i want simply a magnet to oscillation at a given freq and when i want to bump up the voltage the electromagnet becomes stronger pushing and pulling the magnet like an reverse speaker..



sorry if i explaining bad i am trying my best

best regards

 

it is not a energy project its not that big of an deal it is just an experiment im doing dont want to make signification magnetic flux, It work fine when i put 7 or 10 volts trough. the magnet goes forward and when i revers the poles the magnet goes back. now i just need it to do it faster.

but i thank you all for trying i will continue to learn

 

explain why? a speaker is not motionless att 50 hz

 

A speaker is not motionless at 50hz you see it move it ?

 

Ethier case then i am wrong about the hz then it need to be slower.. that what i want to experiment with from 0 and up. And i have riged it so it don´t stuck to the iron core.

 

As i sayd Chris but i would like the circuit to do this to establish to experiment this
to get the right Hz the higher the hz the shorter it oscillation and the lower it oscillate longer

 

Well that would be a problem if it was on a string it is not, The mechanical is working the way i like i get my push and pull in my rig. The only thing i need. and would like answers to is to get my circuit to work.. so i can get my Hz the way i like. In my rig if i put volt between 3-12 dc it pushes the magnet forward then when i turn of the voltage the magnet will go back to its original position because the magnet attract to the iron core. but there is at distance from the magnet and the iron core so when i turn back the voltage the magnet goes forward.

so my original question is the circuit.
thanks

 

Im sorry that you think i am withholding information. That is not my intention i am trying to explain the best to my knowledge. And i don´t think you are novices that´s why i am here to begin with to get the word from people that are experience in electronic

and i am a novice and i can´t even begin to say what it can be called. but yea you could call it a solenoid engine but more a electromagnet engine ? solenoid with a iron core is defined like a electromagnet right?
