Superconductors are becoming popular for use in
A. Generating very strong magnetic field
B. Manufacture of bubble memories
C. Generating electrostatic field
D. Generating regions free from magnetic field
Answer: Option A
Solution (By Examveda Team)
Superconductors are materials that exhibit zero electrical resistance and expel magnetic fields below a certain critical temperature.Strong magnetic fields are generated in applications like MRI machines, particle accelerators, and fusion reactors by using superconducting coils.
These coils can carry extremely high currents without any energy loss due to their superconducting properties, enabling the generation of very strong magnetic fields.
Other options like generating electrostatic fields or regions free from magnetic fields are not related to the primary applications of superconductors.
Therefore, Option A is the correct answer.
