What is used to avoid demagnetization while storing a permanent magnet? Which is the oldest magnet? Where is more magnetic force? In which of the following are the magnetic molecules in the pattern of a closed chain? In which pattern are magnetic molecules found in a magnetized body?
Understand the Problem
The question is asking about various concepts related to magnets in a multiple-choice format. It covers the uses of magnets, types of magnets, locations of magnetic forces, and patterns of magnetic molecules, indicating an assessment of knowledge in the subject of magnetism.
Answer
Keepers, lodestone, both poles, molecular magnet, closed chain.
To avoid demagnetization, keepers are used. The oldest magnet is lodestone. More magnetic force is at both poles of a magnet. Magnetic molecules in a closed chain are found in a molecular magnet. Magnetic molecules in a magnetized body are in a closed chain pattern.
Answer for screen readers
To avoid demagnetization, keepers are used. The oldest magnet is lodestone. More magnetic force is at both poles of a magnet. Magnetic molecules in a closed chain are found in a molecular magnet. Magnetic molecules in a magnetized body are in a closed chain pattern.
More Information
Using keepers helps prevent magnetic field loss during storage. Lodestone is naturally occurring and has been known since ancient times.
Tips
Ensure you do not confuse magnetic storage patterns with electronic ones.
