Magnitude is another name for “size”. You can easily figure out the magnitude of any number by removing the negative sign (giving you the absolute value). For example, the absolute value of -100 is 100, which is also the magnitude.

Scalar variables have magnitude or a numerical value, and not direction. Vectors have magnitude and direction.
