An electroscope is an instrument used to detect static electricity.
An electroscope would detect an electrical charge.

You can't detect the presence of electric current in a conductor with any human sense.

a gold leaf electroscope. if initially charged negatively, the deflection of the leaf with respect to the electroscope is increased if a negatively charged object approaches the electroscope. conversely if a positively charged object approaches, the deflection is reduced. the angle of deflection is proportional to the magnitude of the charge.
An electroscope is an early scientific instrument that is used to detect the presence and magnitude of electric charge on a body. It was the first electrical measuring instrument. The first electroscope, a pivoted needle called the versorium, was invented by British physician William Gilbert around 1600.[1] The pith-ball electroscope and the gold-leaf electroscope are two classical types of electroscope that are still used in physics education to demonstrate the principles of electrostatics. A type of electroscope is also used in the quartz fiber radiation dosimeter.Electroscopes detect electric charge by the motion of a test object due to the Coulomb electrostatic force. The electric potential or voltage of an object equals its charge divided by its capacitance, so electroscopes can be regarded as crude voltmeters. The accumulation of enough charge to detect with an electroscope requires hundreds or thousands of volts, so electroscopes are only used with high voltage sources such as static electricity and electrostatic machines. Electroscopes generally give only a rough, qualitative indication of the magnitude of the charge; an instrument that measures charge quantitatively is called an electrometer.Source : Wikipedia

You can detect the presence of a magnetic field using a compass, which will align itself with the field lines. Other devices such as magnetometers can also detect and measure magnetic fields accurately. Additionally, certain materials, such as iron filings, can visualize magnetic field patterns when sprinkled around the area.

To detect the presence of CI- ion, add silver nitrate solution. A white opalescence to cloudy precipitate of silver chloride will form and confirm the presence of CI- ion.
no electric charge. the nuclear theory at the time explained the atomic masses by assuming the nucleus contained a number of protons equal to the atomic mass number and enough electrons to cancel the charge beyond that of the atomic number of the element.
