A magnetic field can be formed by passing electric current through a wire, and electromagnets work on this basic principal. Electromagnets are used for creating plenty of appliances ranging from motors, speakers, heads for tape drives, and hard disks; here's a brief insight to electromagnets.
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. type of electroscope is also used in the quartz fiber radiation dosimeter. Electroscopes were used by the Austrian scientist Victor Hess in the discovery of cosmic rays. Electroscopes detect electric charge by the motion of a test object due to the Coulomb electrostatic force.
