- Alright mr i will take my book in looker first
- Hello student of 9D today we will discuss our physic about magnetic field and later on i would ask you to take your book and fill the answers.
- So in magnetic field there 4 properties of magnet :1. Magnetic material : magnet attract some material like iron, steel and the other one and it called as ferro-magnetic.2. Magnetic pole: the pole of the magnet is a magnetic material like iron filings 3. North and south poles : if a magnet supported it can swing horizontal where it come to the rest with one pole like N pole is always pointing to the Earth N pole also magnet can use in compass 4. Law magnetic pole: if we put N and N the repulsion will occur same as if we put S and S it is repel to make it attract use N with S
- did you know about the state of properties of magnet ?
- so the meaning of soft and hard magnetic material is :-Soft material : Magnetic material such as iron that magnetise easily but readily lose their magnetism. (easily demagnetised).-Hard material : If a steel that harder to magnetise than iron but stay magnetised
- how about the meaning of soft and hard magnetic material ?
