Important Questions on Magnetism and Magnetic Effects of Electric Current
Write three main characteristics of a magnet.
Shashi was rolling a bar magnet in fine sand. She pulled out magnet from the sand and noticed fine grey particles sticking on the ends of the magnet. However, no particles were sticking in the middle of the magnet. She wanted to know the basic facts clarified such observation with basic facts.
Answer the following questions based on above information:
Why are these fine particles sticking at the ends of the bar magnet but not in the middle of the magnet?
You are given a magnet with no markings, indicating its pole. How can you identify its poles by using another bar magnet with markings?
What will happen if the North pole of a bar magnet is brought near the North pole of a magnet kept on a table?
Explain the term.
