Products in this family are designed to measure the strength of a magnetic field as a variable quantity, as contrasted with similar products that simply detect the presence of a magnetic field having a strength in excess of some limiting value. A common application involves the measurement of the earth\'s magnetic field for direction finding purposes in a manner similar to a traditional compass, and some devices designed to allow measurements to be directly read in terms of physical orientation relative to a magnetic field are available.
