Final answer:
Using a strong permanent magnet and a short copper rod will not create a weak electret.
Step-by-step explanation:
No, using a strong permanent magnet and a short copper rod will not create a weak electret.
An electret is a substance that has a permanent electric charge even without an external voltage source.
It is typically made by subjecting a dielectric material to a high electric field or by heating and cooling it in a specific manner.
The combination of a magnet and a copper rod does not have the necessary properties to create an electret.
