Then one compares the magnitudes to determine which will be subtracted from which, and to determine the sign of the result.

The magnitude of the gradient will determine how fast the temperature rises in that direction.

The magnitude of this depolarization determines whether E-LTP will be induced in the postsynaptic cell.

The position coordinates locate the object on the sky using the techniques of spherical astronomy, and the magnitude determines its brightness as seen from the Earth.

The magnitude and orientation of stress coupled with pressure and temperature conditions determine how a mineral is deformed.

At the receiver, the magnitude of the 1X channel's error determined whether the "fast" channel was to be used instead.

The magnitude of the potential drop determines the acceleration of the charged particles.

With the magnitude of the primary units of electricity thus determined by the kilogram, so too follow many others; namely, the coulomb, volt, tesla, and weber.

The magnitude of the anode bias determines the energy of the incident electrons.

As already noted, the magnitude of an object's visual angle θ determines the size R of its retinal image.
