2. Why do maximum iron filings stick to the ends of the magnet and not to its center?
3. What is the use of magnet keepers?
4. How magnetic properties of a magnet may get destroyed?
6. A carpenter by mistake drops a box of small iron nails into a box of wood shavings. What is the easiest way to separate the two ? (HOTS)
7. How will a sailor find the west direction , with the help of a bar magnet when he is in the sea ? (HOTS)
PLEASE KINDLY GIVE THE CORRECT ANSWER
Answers
Answer:
2.Maximum iron fillings will stick to the ends of the bar magnet because at the ends of the magnet poles are located. The strength of the poles is maximum at the ends of the magnet. A freely suspended magnet always aligns itself in North-South direction.
3.A magnet keeper, also known historically as an armature, is a bar made from magnetically soft iron or steel, which is placed across the poles of a permanent magnet to help preserve the strength of the magnet by completing the magnetic circuit; it is important for magnets that have low magnetic coercivity, such as ...
4.Solution: By hammering the magnet repeatedly.
6.the easiest way is to bring a magnet near the wood shaving. the magnet will attract all the iron nails from the mixture.
7.The sailor will tie the magnet with a thin string and suspend it. On suspending it will turn it's north pole towards north and south pole towards south. Then he can easily find the west direction.
