I settled for an approximate calculation just multiplying the volume suceptibility with the volume. It seems that 1 T is needed to overcome kT at...
I do have access to up to 7 T and if I talk nicely to some people, 11 T so there is no lack of field strength. I am sceptical to why the...
The problem doing electronmicroscopy of nanoparticles (starting out as a solution/suspenion on an organic solvent, then dried) is that they may be...
That's a good start but it gives me the magnetization not the magnetic moment. To get the magnetic moment I can't just multiply with the volume...
It is a bit scary that there actually is a discussion about this. What happens when you take a flask of ethanol (use a round bottom flask or it may...
Does anybody know how to calculate the magnetic moment of a paramagnetic sphere in a magnetic field?
Yes, I actually did the experiment and it breaks. And yes I realize the current is generated as long as you move the sphere, but as soon as it stops...
It is true that the eddy currents take up the energy as a magnetic field, but just transiently, the energy is rapidly converted to heat by the ohmic...
If you have a sheet of copper in a strong magnetic field and try to move it, ring currents will develop that will oppose the motion. Now I wonder, I...
Photons only come in one intensity. Their energy is proportional to their frequency. Intensity of light corresponds to the number of photons emitted...
You also need Semons cross-section for birdshit collisions. I guess we can treat the bird shits as point particles.
You must mean the time constant of decay. That is given by the linewidth from the uncertainty relation. If I remember correctly it should come out as...
Referring to my earlier posting, Yes, it it exactly the same thing! I don't know why you talk about destuctive interference here. That must be a...
What you are doing is subtraction from infinity and that has no effect on an infinite number so the number would stay infinite. Either you have...
Actually, all cooling processes consume energy. Put your hand at the back of your refrigerator. You use the energy to move heat from one place to...
It is a fact that the body is indeed reacting to sensory input. If you look at a lemon your mouth will water. If you taste something sweet your...
To reason about complicated matters like the brain, a good starting point is a null-hypothesis. This would be the hypothesis that assumes as few...
I belive the origin of the tachyon idea is that general relativity only prohibits particles with mass to move exactly at the speed of light. If they...
Kumar, I am not sure if I have explained this to your satisfaction. It seems that we got a little sidetracked in the last post. The placebo effect is...
This is getting curiouser and curiouser. The burden of proof always lies with the person who proposes a theory. You never prove theories, it is just...
Separate names with a comma.
