Onnes, a substance with this property displays the Meissner Effect when exposed to a magnetic field.
In 1957, BCS theory demonstrated that this phenomenon is caused by Cooper pairs condensing into a ground state. Discovered in 1911 by Heike Kamerlingh- Onnes, a substance with this property displays the Meissner Effect when exposed to a magnetic field. It occurs when a material is cooled beyond a critical temperature, and it is used to create powerful electromagnets used in particle accelerators and Maglev trains. FTP, name this phenomenon in which a substance loses all electrical resistance.
In 1957, BCS theory demonstrated that this phenomenon is caused by Cooper pairs condensing into a ground state.
