Advanced and Delayed magnetic field's.

[MarkE]

Iron filings are one of the worse things you can use to show a magnetic field,and the reason for that i have explained before. I would like to see an actual magnetic mapping video,insted of countless cartoon pictures showing incorrect field shape of a PM magnet. I will continue this debate on the magnetic miths and misconceptions thread-where it belong's.

Tinman iron filings have been used to correctly depict magnetic fields for over 150 years.  If you are worried that iron filings distort the fields that they map, then you can disabuse yourself of that idea by simply  using  lower densities of particles, and/or only using them in selective locations, or by doing some math to see that short of immersing a magnet into a solid vat of extremely fine particles, the density can never be high enough to make any substantial difference.

    Oh dear Tinman, you're a disappointment  to me. You showed so much promise and it
  seems to be evaporating into the aether.

Im not out to have your approval in any way shape or form. Are you that good that you can judge other people Minnie?- i think not. MarkE is the disappointment here,as he wont even take the time to draw three simple bloody pictures of what he thinks a magnetic field looks like around an electromagnet,but like others,demands that we show devices and tests to prove what we say is true.. I also gather that you are much the same-love shelling out the demands of proof,but have no input towards experiments conducted by your self. To sit there at your keyboard and think you have the right to judge me is nothing short of bullshit.Im yet to see any of your fancy work here minnie,or are you an armchair jocky like Mark,that cant extend the courtesy of a simple drawing to some one that has gone out of his way to help,show and deliver on many experiments. Maybe you would care to show me the magnetic field around an electromagnet?.

[minnie]

   Yeah, I'm lucky to be able to use a keyboard. I owe a lot to magnetic research having
had a serious back injury needing precise surgery and this being made possible by analysis
  of  MRI imaging.
        Do you think you could teach those designers a thing or two about magnets? What
  about the people at CERN and similar establishments, do they know anything?
       I've seen it so often, someone has an idea, page two and a scientific answer is given
  as to what is wrong. Then, one hundred and fifty pages later the topic  just dies.
     I still do love your anti -gravity demo, it's got plenty perplexed!

Please dont present my experiments as things they are not. I would like to know where i presented an anti gravity device?. Maybe you would give me the pleasure of answering the question i just asked mark on the magnetic miths and misconceptions thread,about the pancake coil around the electromagnet.

I to broke my back,and smashed my knee to pieces in a motorcycle accident,and it took me months to learn to walk again after surgery. But sheer determination got me back on my feet,as there was no way i was going to live my life not being able to do the things i love. I now have my limits(which some times i exceed and pay the price for for the next 2 weeks),but i always find a way around things i can no longer do. I find it hard to believe you would judge me before i have a chance to show why i think magnetic fields are not correctly represented.
