- Dude!.. What is the teacher explaining about? I wasn't paying attention. What does she mean by properties of magnets
- Hmm...Well there are 4 properties of magnet which are:1. Magnet attracts ferro magnetic material like iron and steel.2. Like magnet poles repel each other while unlike poles attracts each other.3. A suspended magnet always come to rest in north-south direction.4. The poles of the a magnet are in pairs
- Oh, what about soft and hard magnetic materials? are they spongey magnets and magnets that are strong like a rocks or brick?
- No silly, Soft magnetic materials such as iron are those that magnetise easily but readily lose their magnetism while hard magnetic materials are those such as steel that are harder to magnetise than iron but stay magnetised.
- So if we talk about magnetic field... does it mean the space surrounding a magnet where it produces a magnetic force?
- Exactly.
- I heard we could also map magnetic fields. How do we do that?
- Of course we could, There are two ways we could do it. First is by plotting compass method, where we place the plotting compass near the magnet on a piece of paper and mark the direction the compass needle points. Then movethe plotting compass to many different positions in the magnetic field, marking the needle direction each time.
- How about the second way?
- Well the second way is the Iron fillings method, where we place a piece of paper over a magnet and sprinkle iron fillings onto the paper. Then gently tap the paper to spread the fillings out and observe the results.
- Kriingg Kriiing!! (bell rings)
- Thank you so much for the today, I really appreciate your help
- hey, last question...What is neutral points in magnets?
- A neutral point of a magnet is which the resultant magnetic field isalways zero.It is obtained when the north pole of the magnet points to the south and the magnet in the magnetic meridian.
