Gaussian units use the statCoulomb for charge which is defined in such a way as to remove the proportionality constant from Coulomb's law:atomicpedals said:I'm going in circles on units (or perhaps more accurately different unit systems). The two my professor has chosen to work in are Gaussian units and MKSA units. My problem is one of lack of understanding; are the units of measure for electric and magnetic fields in these systems:
Gaussian: E = n/C; B = n-s/C-m
MKSA: E = n/C; B = w/m^2
Electric fields are caused by stationary electric charges, while magnetic fields are caused by moving electric charges. Electric fields are measured in volts per meter (V/m), while magnetic fields are measured in tesla (T) or gauss (G).
Electric and magnetic fields are related through Maxwell's equations, which describe the fundamental relationship between electric and magnetic fields. In simple terms, a changing electric field can create a magnetic field and a changing magnetic field can create an electric field.
Electric fields are measured in volts per meter (V/m), while magnetic fields are measured in tesla (T) or gauss (G). In some cases, smaller units such as millivolts per meter (mV/m) or microtesla (µT) may also be used.
Electric fields are affected by the dielectric constant of a material, which measures how easily electric charges can move through it. Magnetic fields are affected by the permeability of a material, which measures how easily magnetic fields can pass through it. Different materials can have different effects on the strength of electric and magnetic fields.
Common sources of electric fields include power lines, electrical appliances, and electronic devices. Magnetic fields are often produced by the same sources, as well as by magnets and the Earth's magnetic field. In general, any device that uses electricity can produce electric and magnetic fields.
