    Gauss Levels
AI Thread Summary
There is significant confusion regarding safe levels of Gauss for everyday exposure, with various articles and books providing conflicting information. The human limit is understood to be 2000 Gauss, but many sources suggest that low energy electromagnetic fields do not pose a health risk. Studies indicate that magnetic fields up to 10,000 Gauss, such as those found in MRI machines, have no adverse effects on biological tissues. Everyday devices like cell phones emit much lower levels of magnetic fields, which are considered too weak to have any impact. Overall, skepticism remains regarding the biological effects of low energy electromagnetic fields on human health.

All the articles and books I have read conflict with one another in safe levels of Gauss. I understand the Human limit is 2000 Gauss. Does anyone know what levels of Gauss are acceptable for everyday exposure? As I said, all reports I have read conflict one another.

The reason there is no consensus as to what level of electromagnetic field is safe is because there is really no evidence that em fields are a danger to human health.

Although all biological processes are complex, there is every reason to be very skeptical that low energy em fields cause any biological effects. In order to have a biological effect, an em field, at a very minimum must be able to break a hydrogen bond. Compare the bonding energy of a hydrodgen bond to the energy of a photon radiating from a powerline, for example. The heat energy in a cell, which is essential in order for biological processes to operate, produces much higher energy photons.

I have found the same thing, I have not found two sources that say the same thing as far as what is safe. My cell phone puts out 98.2G (using a LakeShore 410 Gaussmeter).
 
Biological studies by Stick and Hinkelmann of the effects of static magnetic fields have found that magnetic fields up to 1 Tesla (10,000 Gauss) have no effect on tissue, blood flow, etc. One Tesla is huge. You only get magnetic fields like that in special medical machines (MRI) or in special laboratories specifically designed to create fields that strong. If you ever find yourself near such things, you are briefed on the potential risks of strong magnetic fields. Although most biological tissue is diamagnetic, the response is so weak that everyday magnetic fields, such as from a cell phone, loud speakers, or fridge magnets are far to weak to have any effect.
 
Thread 'Gauss' law seems to imply instantaneous electric field'
Imagine a charged sphere at the origin connected through an open switch to a vertical grounded wire. We wish to find an expression for the horizontal component of the electric field at a distance ##\mathbf{r}## from the sphere as it discharges. By using the Lorenz gauge condition: $$\nabla \cdot \mathbf{A} + \frac{1}{c^2}\frac{\partial \phi}{\partial t}=0\tag{1}$$ we find the following retarded solutions to the Maxwell equations If we assume that...
Maxwell’s equations imply the following wave equation for the electric field $$\nabla^2\mathbf{E}-\frac{1}{c^2}\frac{\partial^2\mathbf{E}}{\partial t^2} = \frac{1}{\varepsilon_0}\nabla\rho+\mu_0\frac{\partial\mathbf J}{\partial t}.\tag{1}$$ I wonder if eqn.##(1)## can be split into the following transverse part $$\nabla^2\mathbf{E}_T-\frac{1}{c^2}\frac{\partial^2\mathbf{E}_T}{\partial t^2} = \mu_0\frac{\partial\mathbf{J}_T}{\partial t}\tag{2}$$ and longitudinal part...
