Electric currents, permanent magnet, copper wire: No, the scenario you drew up there will not magnetize your iron chunk at all. Resistivity is represented by the Greek letter rho (I ll use p) and is defined to be p = E/j where E is the electric … Read Article

Charge Density – Wikipedia, The Free Encyclopedia
ρ in electromagnetism for wavelength, electrical resistivity and conductivity. Within the context of electromagnetism, the subscripts are usually dropped for simplicity: λ, σ, ρ. Other notations may include: the length of a segment of wire depends on velocity of observer, … Read Article

Thermal Conductivity – Wikipedia, The Free Encyclopedia
The reciprocal of thermal conductivity is thermal resistivity, usually expressed in kelvin-meters per watt (K·m·W −1). For pure metals such as copper, silver, etc. l is large, so the thermal conductivity is high. … Read Article
