Qualitative Statement of The Law
The most widespread version of Faraday's law states:
The induced electromotive force in any closed circuit is equal to the negative of the time rate of change of the magnetic flux through the circuit.
This version of Faraday's law strictly holds only when the closed circuit is a loop of infinitely thin wire, and is invalid in other circumstances as discussed below. A different version, the Maxwell–Faraday equation (discussed below), is valid in all circumstances.

Famous quotes containing the words qualitative, statement and/or law:
“You ask: What is it that philosophers have called qualitative states? I answer, only half in jest: As Louis Armstrong is said to have said when asked what jazz is, ‘If you got to ask, you ain’t never gonna get to know.’”
—Ned Block (b. 1942)
“Children should know there are limits to family finances or they will confuse “we can’t afford that” with “they don’t want me to have it.” The first statement is a realistic and objective assessment of a situation, while the other carries an emotional message.”
—Jean Ross Peterson (20th century)
“Without doubt God is the universal moving force, but each being is moved according to the nature that God has given it.... He directs angels, man, animals, brute matter, in sum all created things, but each according to its nature, and man having been created free, he is freely led. This rule is truly the eternal law and in it we must believe.”
—Joseph De Maistre (1753–1821)
