ETA, we should pay close attention to the research being done with magnetism and the human brain. Transcranial Magnetic Stimulation studies show that a strong magnetic field generated right next to a subject's head will interfere with their ability to think properly.

It's not really the strong magnetic field that causes those effects, it's the rapid change in the magnetic field, inducing an electric current on the brain under it.

ArMaP,

Do we have to do this again?

Without the influence of the magnetic field produced by the appliance, this would not happen.

ArMaP,

Do we have to do this again?

I'm sorry, but when I see someone that appears to not know something about the subject they are talking about I try to correct them.

Without the influence of the magnetic field produced by the appliance, this would not happen.

True, but it's the sudden change that creates the effect, not the presence of the magnetic field itself. A static magnetic field of the same intensity would not create that effect.

What is TMS?
TMS is based on the principle of electromagnetic induction. Michael Faraday showed that when an electrical current is passed through a wire, it generates a time-varying magnetic field. If a second wire is placed nearby, the magnetic field induces electrical current flow in that second wire. In TMS, the 'first wire' is the stimulating coil and the 'second wire' is a targeted region of the brain.

rTMS: How it works

A typical rTMS session lasts 30 to 60 minutes and does not require anesthesia.

During the procedure:

- An electromagnetic coil is held against the forehead near an area of the brain that is thought to be involved in mood regulation.
- Then, short electromagnetic pulses are administered through the coil. The magnetic pulses easily pass through the skull, and causes small electrical currents that stimulate nerve cells in the targeted brain region.

Because this type of pulse generally does not reach further than two inches into the brain, scientists can select which parts of the brain will be affected and which will not be. The magnetic field is about the same strength as that of a magnetic resonance imaging (MRI) scan. Generally, the person feels a slight knocking or tapping on the head as the pulses are administered.

When you see a picture, hear a sound, or think of something, electric currents driven by electric fields will flow inside certain parts of your brain. TMS causes similar electric currents in the brain, but the neurons are instead activated with a magnetic pulse from a coil that is placed over the head. In TMS, the electric fields are generated by electromagnetic induction. Therefore, they travel effortlessly through the scalp and skull, which makes TMS an easy, painless, and non-invasive way to stimulate the brain.

I don't understand why you bolded the word "magnetic", didn't you notice that I agreed that magnetism is (obviously) needed?

I also suppose you didn't notice all the references to changes in the magnetic field, so I will bold the important parts you missed.

Electromagnetic or magnetic induction is the production of an electromotive force (i.e., voltage) across an electrical conductor due to its dynamic interaction with a magnetic field.

This is the principle in which transformers are created:
an alternating current on the primary coil creates a alternating magnetic field. This alternating magnetic field, acting over the secondary coil, creates an alternating current.

If you connect a transformer to direct current, it creates a constant magnetic field on the primary coil and a transient (only for a few milliseconds) direct current on the secondary coil when you connect the current. As soon as the magnetic field stabilises the current on the secondary coil stops flowing.

Anyone that has learned about electricity (like I did) can tell you that's one of the first things we learn.

ArMaP,

I put you on Ignore this afternoon, so don't waste your breath.

I am familiar with magnetic induction on a coil or piece of wire to create voltage.

In fact attaching voltage to any piece of wire will create magnetic lines around it.

However this does not apply to non ferrous metal.

I am wondering how these principles of voltage and magnetism apply to brain matter, which is non ferrous as well.

Brain matter is not a good conductor like a piece of wire is, or wire wound into a coil.

The brain matter itself is non conductive, but your nervous system itself is electric in nature...

Yes but the quoted material said the magnetism induced a voltage into the brain.

I don't doubt that a magnetic field could disrupt nervous system signals being passed, but using brain matter as a piece of wire to induce voltage does not seem likely.


eta: Note that magnetic fields have no effect on wood, bone, stone or other non ferrous material.

There is a reason that magnets stick to refrigerators and not your skin.

Magnetism and voltage will affect non ferrous metals such as copper (for copper wire), but again the key word is metal for wire and electromagnetic affects to be achieved.

I see no evidence of metal in brain matter to accomplish this.

[ArMaP]

Yes but the quoted material said the magnetism induced a voltage into the brain.

I see this is something apparently difficult to understand, or I haven't been able to explain it well.

What creates a current in the brain (or whatever) is the change in the magnetic field, not the magnetic field itself.

eta: Note that magnetic fields have no effect on wood, bone, stone or other non ferrous material.

You're looking at the wrong effect, that's why you can't see how it works.

A changing magnetic field creates a changing current (called Foucault current) that tries to oppose it on any conductive material, regardless of being ferromagnetic or not.

An alternator works on the same principle, with one or more magnets moving close to fixed (non ferromagnetic) copper coils (or moving coils near fixed magnets), creating an inducted current on the coils. If you make a copper coil and put it over a magnet no current will come out of the coil, except when you move the coil or the magnet. The faster the movement the stronger the resulting currents. No movement (no change in magnetic flux), no currents.

A transformer also works on the same principle, and you can make a transformer without a ferromagnetic core, it will make the induction more difficult because the magnetic field created will be weaker, but as it will still create a changing magnetic field it will still create Foucault currents on the secondary coil and it will work.

The old electromechanical electricity meters we have (or had, as in my case) at home also work by the same principle, with an alternating magnetic field proportional to the current being used at home creating Foucault currents on the (usually) aluminium (non ferromagnetic) disc. Those alternating currents create their own magnetic field, opposing the magnetic field that created them, and so they make the disc rotate.

Although not the same principle, you can compare it with the way a  hi-fi speaker works: we can only ear the sound when there's a change in the magnetic field created in the speaker by a changing current, a constant magnetic field will move the coil inside the speaker to a fixed position and it will not make a sound. Foucault currents act in the same way, you need a change in the source magnetic field to get a change in the resulting conditions near the coil.

I hope I haven't complicated things further.

That is the problem right there, "any conductive material". I don't recall brain matter ever being described as conductive material.

is it a superconductor or a crap conductor?
