... If a rod is charged then all the charges on the rod are repelled from each other and will try to escape from the material if they can. If the material is an insulator like plastic then the charges are not able to move and so remain on the material. However if you touch the material with your fingers ...

Fundamentals of magnetic field
... The flux change occurs either because the magnetic field is changing with time (transformer inductance) or because the wire loop is moving relative to a magnetic field (motional inductance). The Faraday's induction law describes both phenomena. a) If a wire loop is fixed and the flux is varying with ...

Galvanometer
A galvanometer is a type of sensitive ammeter: an instrument for detecting electric current. It is an analog electromechanical actuator that produces a rotary deflection of some type of pointer in response to electric current through its coil in a magnetic field.Galvanometers were the first instruments used to detect and measure electric currents. Sensitive galvanometers were used to detect signals from long submarine cables, and to discover the electrical activity of the heart and brain. Some galvanometers use a solid pointer on a scale to show measurements; other very sensitive types use a miniature mirror and a beam of light to provide mechanical amplification of low-level signals. Initially a laboratory instrument relying on the Earth's own magnetic field to provide restoring force for the pointer, galvanometers were developed into compact, rugged, sensitive portable instruments essential to the development of electrotechnology. A type of galvanometer that records measurements permanently is the chart recorder. The term has expanded to include use of the same mechanism in recording, positioning, and servomechanism equipment.
