Questions & Answers

Q: What are some examples of artificial magnets?

Artificial magnets can come in shapes such as bar magnets, shrew magnets, and cylindrical magnets.

Q: Are all materials attracted to magnets?

No, only materials that are magnetic, such as iron, cobalt, and nickel, are attracted to magnets. Paper is not a magnetic material.

Q: How were magnets used in the past for finding direction?

Sailors would suspend a magnet to find direction, as magnets always align in the north-south direction, helping them navigate.

Q: How many poles do magnets have?

Magnets have two poles: the North Pole and the South Pole, which have opposite charges and attract each other.

Q: Are similar poles or different poles attracted to each other?

Similar poles, such as North Pole to North Pole, repel each other, while different poles, like North Pole to South Pole, attract each other.

Q: Where are the iron filings located on a bar magnet?

The maximum iron filings are seen towards the ends of a bar magnet, where the poles are located.

Q: Can a compass be used to find east-west direction?

Yes, a compass will always align in the north-south direction. By knowing the North Pole, one can determine the East and West directions.

Q: Is rubber a magnetic material?

No, rubber is not a magnetic material. It does not get attracted by a magnet.

Summary & Key Takeaways

  • Artificial magnets can be made in different shapes, such as bar magnets, shrew magnets, and cylindrical magnets.

  • Magnetic materials, such as iron, cobalt, and nickel, are attracted to magnets, while materials like paper are not.

  • In the past, sailors used magnets to find direction, as magnets always align in the north-south direction.

  • Magnets have two poles: the North Pole and the South Pole.
