General magnet magnetic induction intensity is not high, not formation damage to human body.
If you are in a part of the job for a long moment, it is still in discussion, like acupuncture, same as it is more secrets than acupuncture.
But as a result of the CRT is scanned of electronic current under the influence of magnetic field, thus to CRT trouble happened.
Plus magnetic field distorts imaging tube in the magnetic field, the electron flow against normal scanning track.
Cause picture distortion (
Right and wrong and color display)
And brown spots (
Only color display)
General multimedia speakers use magnetic shielding skills, placed around the CRT will not form any effect, but take out the speaker magnet for CRT scan will see significant role.
But, it will not form any damage to the use of CRT life, most only caused by single point burn long time picture distortion.
If the magnet after removal of drawing deformation, still be attributed to the appearance of the metal tube palette is magnetized, only need to display the demagnetization effect is open, demagnetization has been removed, so the old monitor will need to open a few switch back.
About qualified hard disks, magnetic shielding skills properly.
You can't through the magnetic field from the outside to blow up it.
Experts are calculated, if the magnetic field reached the intensity, was enough to suck out all the iron in your body.
Floppy disk and tape is true we should take care of that, but it is who still use floppy disks to deal with their bank CARDS (
With a magnetic stripe)
What about the mainboard or other, you don't need to be careful of what would be a bad result.
Once friends say to the problem of phone calls, not due to the magnetic field, but due to the change of electromagnetic field.
Changing the electromagnetic field of electromagnetic radiation into the surrounding space, and a magnet, the stable magnetic field, not outward radiation of electromagnetic wave.
Needless to say, now the electromagnetic signal trouble appliances electromagnetic compatibility of these concepts is mainly aiming at problems such as electromagnetic wave pollution to power network, rather than for human health problems.
When the phone around on a tape recorder, tape recorder called noise is very big, much worse than shortwave radio.
As for the computer, I didn't try, also have never seen.
Let's try it one day.
But I don't think this is what, unless the machine is too bad.
High frequency) electromagnetic waves
The damage to the international people from different countries are still in discussion quickly, what is the cell phone radiation standard, etc. , there are many.
However, if a person long time exposed to high intensity in the electromagnetic field (
Note that this is a constantly changing electromagnetic fields, rather than a stable magnetic field)
He may cause cancer.
