Question

The scientific principle involves in production of ultra high magnetic fields is

• A. Super conductivity
• B. Digital logic
• C. Photoelectric effect
• D. Laws of thermodynamics.

Answer 1

The correct option is A Super conductivity

The application of a sufficiently strong magnetic field to a superconductor will, in general, destroy the superconducting state. Two mechanisms are responsible for this. The first is the Zeeman effect which breaks apart the paired electrons if they are in a spin-singlet (but not a spin-triplet) state. The second is the so-called 'orbital' effect, whereby the vertices penetrate into the superconductors and the energy gain due to the formation of the paired electrons is lost. Hence, if we have more conductivity it will be easier for the production of ultra magnetic fields. Hence, option A is the correct answer.
