6. What happens when a permanent magnet is heated? When it is cooled will it retain
its original magnetic properties? (2 marks)
Answers
Answer:
When the permanent magnet gets heated at higher temperatures, it tend to loose it's magnetic properties. When it is cooled down with strong fields of magnetism , it retain its property
Answer:
when a magnet is heated there will no change in its shape but it will become weak and if it is heated up to curie temperature it losses all of its magnetism
Explanation:
heating does not affect the shape of a magnet but when a magnet is subjected to the heat it experiences a reduction in its magnetic field the particles inside the magnet begin to move faster actually heat causes the particles of the magnet to confuse and misaligns the domains of the magnet causing the magnetism to decrease.
when the temperature is heated up to curie temperature at around 80-degree Celcius it will become demagnetized permanently.
