Meissner Effect
The Meissner effect is the expulsion of a magnetic field from a superconductor during its transition to the superconducting state.
Motional EMF
This demonstration exhibits the concept of motional emf. When a conductor is moved through a uniform magnetic field,
an emf
Forces on conductors inside magnetic fields and between current carrying conductors
This demonstration exhibits forces on current carrying wires when placed inside a magnetic field. The magnetic field can come in
Oersted’s law
Ørsted’s law, or Oersted’s Law states that when a steady electric current passes through a wire it creates a magnetic
Temperature Dependence of Resistivity of a Metal Wire
This apparatus shows the effect of temperature on resistance of a common metal, such as copper. The idea is simple.
Semiconducting behaviour of thermistor
This demonstaration shows the semiconducting behaviour of a thermistor. A thermistor is a temperature-sensing element composed of semiconductor material which
Galton Board
Galton’s Board, named after the English psychometrician Sir Francis Galton (1822-1911), is also called a Quincunx or bean machine.
