Modern electroscopes usually use balls made of plastic. In order to test the presence of a charge on an object, the object is brought near to the uncharged pith ball. If the object is charged, the ball will be attracted to it and move toward it. The attraction occurs because of induced polarization [6] of the atoms inside the pith ball.

English: Diagram showing how a pith-ball electroscope works. The molecules (yellow ovals) that make up the pith ball (A) consist of positive charges (atomic nuclei) and negative charges (electrons) close together. Bringing a charged object (B) near the pith ball causes these charges to separate
The number of degrees twisted to bring the balls back together is in exact proportion of the amount of charge of the ball of the carrier rod. Francis Ronalds , the inaugural Director of the Kew Observatory , made important improvements to the Coulomb torsion balance around 1844 and the modified instrument was sold by London instrument-makers.

The charged aerosol detector (CAD) is a detector used in conjunction with high-performance liquid chromatography (HPLC) and ultra high-performance liquid chromatography (UHPLC) to measure the amount of chemicals in a sample by creating charged aerosol particles which are detected using an electrometer.
