What is the magnetic field?

saq05 Says:

Apr 27, 2008 - In the video it said magnetic field lines start at north and end at south. ACTUALLY unlike electric field lines, magnetic field lines DO NOT "start" or "end" anywhere. you can imagine them like continuous closed loop that has no point to begin and end.

Rather you can imagine magnetic field lines as a continuous closed loop.

May 10, 2008 - ok, but you stated the question 'what is the magnetic field?' it's not just lines on a paper, leading from N to S. what is behind the phenomenon? i was realy curious what you were going to show, when i saw the title you put on your video.

May 14, 2008 - I could be wrong, but magnetic field lines sure look a lot like standing wave patterns to me. When these waves pass through matter with the appropriate arrangement of atoms then they are either pushed together or pushed apart. If this is correct, then perhaps one could reproduce these standing waves (a magnetic field) using simple wave modulation (I.E. radio waves) instead of coils of wire to force the atoms to spin together.

May 16, 2008 - greatso can i make a gigantic magnetic rinkand have some reversed magnetic shoes and just start gliding aroundwho wouldn't want to try that

Jul 6, 2008 - dude. ofcourse you can!the only problem is the amount of magnets you need.therefor people would make an electromagnetic rink

Jul 15, 2008 - does it matter how many lines? Wouldn't that be relative to the size of the particles that were making up the matter of the magnet? In other words the resolution of the matter smaller atomical size = more field lines.Then again, smaller particle size could = less definitive lines and tend to gauss blur into a magnetic mass depending on the medium it was existing in. Or greater overall magnetic force could compress the field in tighter which could give the appearance of more lines.

Jul 16, 2008 - Think of the lines like contour lines on a topographical map. There is no correct number of lines to draw. In fact, there are an infinite number of lines one could draw. What is important is that they communicate the proper relationship between one place and another. Where the magnetic field is stronger there are "more" lines. This is analogues to contour lines, where the mountain is steeper there are more lines. How many you have depends on the scale you choose.

Sep 2, 2008 - Can the existing magnetic properties of tin be negated by inducing a negative charge on a semiconducting ceramic substrate preventing the movement of .022" Tin95.5/Silver4.0/Copper.5 balls?

Sep 17, 2008 - are field line real physical things? i dont think so, i think they r just a representation of the relation, like a probability wave doesnt exist its just a representation of a relatio (calculus).am i wrong?

Sep 19, 2008 - does a magnetic field have any effects to health? or electric magnetism? please help me i'm just a little kid searching for answers lol

Sep 23, 2008 - intresting can you explain me a way to make a magnetic feild?im just a kid trying to make a go cart using magnetic feilds lol im tryin to improve my dad...

Oct 4, 2008 - but what is the mechanism of cycling the electric field? only I know ;D

BenZeneProject Says:

Oct 10, 2008 - excellent. I even like the music. Go replace Bill Nye.imu, magnets have a direct bipolar effect on the etheric fluid, unlike other substances which exhibit monopole, paramagnetic or radionic properties. Thus the magnets' ability to align itself to any other magnetic field creates never ending questions.gravity==majority monopole material?magnetism==majority dipole material?I'm not sure if somebody else said this before me or not, but it seems axiomatic.magnets seem to be special mass.

Oct 18, 2008 - a bit over simplified.

Nov 12, 2008 - Good video but didn't help me =/PLEASE PLEASE PLEASE WILL SOMEONE SEND ME A VIDEO ABOOUT HOW THE MAGNETIC FIELD AFFECTS THE DIRECTION THAT A COMPASS POINTSi will be really grateful if someone did but it has to be by tonight xx

colon98765 Says:

Nov 12, 2008 - the magnetic field of the earth exerts a force on the compass needle (which is made of a metal that is magnetic) this force exerts a torque on the needle which causes it to spin in the direction of the magnetic field once it's in line with the field (that's when the needle is pointing directly at the earth's magnetic south pole, which is atually the geographic north pole) it will stay there unless if there is a stronger field thats affecting the compass.

Nov 18, 2008 - So-called magnetic attraction is actually voidance. Check it out at 1:50. When the two opposite poles meet they void each other and their poles are extended to the extreme opposite ends of their newly combined magnetic fields. This demonstrates the proof of magnetic voidance and not magnetic attraction. Magnetism's only function is to repel and electricity is actually the attractive force. Academic explantions about magnetism are corrupted by this huge perceptional error. Walter Russell rules!
