In electromagnetism, permeability is the measure of magnetization that a material obtains in response to an applied magnetic field. Permeability is typically represented by the (italicized) Greek letter μ. The term was coined by William Thomson, 1st Baron Kelvin in 1872, and used alongside permittivity by Oliver Heaviside in 1885. The reciprocal of permeability is magnetic reluctivity.

The severance of the tree roots when the trees are cut changes the soil biology. To study questions of nutri- tion simultaneously with light intensity and quality the "semi-field" technique is convenient and efficient.
