ideasrule said:But a superconductor doesn't have a magnetic field. It actively tries to counteract any changes in the magnetic flux passing through it, leading to the Meissner effect.
xcvxcvvc said:By Ampere's law, is not the magnetic field produced by a conductor proportional to the current through it? Would not then a superconductor have a bigger magnetic field compared to a regular conductor due to the lack of electrical resistance?
A "12 year old simple question" refers to a question that is typically asked by a 12-year-old and is considered easy or straightforward to answer.
The age of 12 is considered significant because it is often seen as a transition period between childhood and adolescence. At this age, children are starting to develop more critical thinking skills and may begin to ask more complex questions.
Examples of "12 year old simple questions" may include: "Why is the sky blue?", "How do plants make food?", or "Why do we have seasons?" These questions are often asked by curious 12-year-olds and can be easily answered by a scientist.
While a "12 year old simple question" is typically asked by a 12-year-old, a "child's question" can refer to any question asked by a child of any age. However, both types of questions may be considered simple and easy to answer.
Encouraging children to ask questions is important because it helps them develop their critical thinking skills, expand their knowledge and understanding of the world, and fosters creativity and curiosity. It also allows them to actively engage in their own learning and can lead to a deeper understanding of complex concepts.
