Ampere’s Law The line integral of the magnetic flux around a closed curve is proportional to the algebraic sum of electric currents flowing through that closed curve; or‚ in differential form curl B = J. This was later modified to add a second term when it was incorporated into Maxwell’s equations.

something and nothing. Differential thresholds refer to the intensity difference needed between two stimuli before people can perceive that stimuli are different. Thus‚ the differential threshold is a relative concept. Weber’s law (1834) states the positive relation between the first stimulus and the second stimulus. The greater the initial stimulus‚ the stronger the additional intensity need for the second stimulus to be perceived as different. Absolute threshold Differential threshold Amount of
