Discussion Overview

The discussion centers around the construction of a powerful antenna designed to emit electromagnetic waves in the frequency range of 1-50 MHz, specifically for an experiment related to nuclear magnetic resonance (NMR). Participants explore the feasibility of using a solenoid for this purpose and seek assistance in achieving the desired power output.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant expresses a desire to create a powerful antenna for emitting waves in the 1-50 MHz range, indicating that a normal solenoid is insufficient.
  • Another participant questions the purpose of the antenna and its relation to a solenoid.
  • A participant suggests that it might be possible to emit electromagnetic waves with a solenoid, seeking clarification on this point.
  • There is a suggestion that the intended use of the antenna may relate to constructing an MRI machine or a similar device.
  • A participant clarifies that their goal is to observe the NMR phenomenon and emphasizes the need for assistance in building the antenna.

Areas of Agreement / Disagreement

The discussion contains multiple competing views regarding the use of a solenoid for emitting electromagnetic waves, and the participants have not reached a consensus on the best approach to constructing the antenna.

Contextual Notes

Participants have not fully explored the assumptions regarding the power requirements for the antenna or the specific design considerations necessary for effective emission in the desired frequency range.

Hey,

So I want to make an antenna which emits powerful waves in the frequency range of 1-50 MHz.

Yet I don't know exactly how powerful those waves should be, but a normal solenoid is not enough... :P It should be really powerful... :D

Any help is welcome :)

What is the purpose of this and what does a solenoid have to do with it?
 
Well... I might be wrong but I thougt that it was actually possible to emit EM waves with a solenoid; isn't that the case?

oh and yeah... I need it actually to do an experiment about nuclear magnetic resonance

So you want to make an MRI machine then? Or something similar?
 
well if you put it like that, yes... but I mean everything I want to do is observing the NMR phenomenon and all I need for the moment is such an antenna... so could anyone help me?
