Magnetic Radiation

lescolliershustoke@virginmedia.com

Hi

     a question :>

 

I have a solenoid and it has a certain range to it, i.e. the magnetic field does not go on fro ever for practical purposes.

 

I can adjust the design to gain more range, I can wind more turns on the armature but this won't extend the range if the core material saturates out. I can up the voltage and hence the current, but this creates more heat that I have to dissipate, and I want to power from a battery at the end of the day. So I am trying to get the longest range I can from 10 to 14 volts.

 

 

Does anyone have an answer on which parameter to try moving first assuming the range I have is not good enough.

 

regards

    All methods to do what you want do do have already been mentioned on this thread as of at least a day ago. All options to increase the range of the solenoid

    by increasing the reach of the magnetic field (in this case this is what it should really be called) will require an increase in power, it's the law. At this point since

    you are the only one that knows what you are actually trying to do (although you have been asked twice now to better explain it) and all the options have been

    on the table for a while, no one else can add much to the discussion about your specific case or come to any kind of reasonable conclusion as to what would

    probably be the best thing to do. So at this point it's up to you to figure out which method you want to use, or provide more information on what you are trying

    to do so the others that may have a better understanding of magnetics can provide further guidance.

    Hello Everyone

                             can I start by thanking you all so much for your contributions I have plenty to go at.

     

    I am sorry I have been a bit cagy with details My patent agent said that I must not divulge anything about the device as it may prejudice my patent application which I will make in due course. That's not for one minute inferring that you might want to copy the idea, just simply that if you did not know the content you could not have been the one to spill the beans, does that make sense, I hope so and please please do not take offence. Non intended.

     

    I will come back when I done some more work and let you know how I got on. Untill  then Many thanks for the input. Sufficient to say that if I am successful we may have collectively saved a life.

     

    Regards

    Hi Les,

     

    Thanks for clarifying your post.

     

    I understand, having been through the patent process, I fully understand the intense level of secrecy involved.

     

    Good luck with your idea and I am very interested in what you end up with.

     

    Please keep us informed and let us know if you need more support.
