MAGNETISM

Hy friend of physics, this time we will try to see what the pattern is formed from the powder - iron powder .....

want to know how the pattern?????


PLEASE IN TRIAL

Knowing the magnetic lines of force around a magnet

Tools and materials

1. bar magnet

2. The white paper

3. iron powder

Step trial

1. Place the bar magnet under a sheet of white paper

2. Sprinkle iron filings on paper

3. The pattern formed by the iron filings are magnetic lines of force

Magnetic lines of force towards the south pole outside the magnet and leave the north pole, in the direction of the magnetic lines of force of the magnetic north pole south to the pole



this is picture of pattern of iron filings showing magnetic field













lines of magnetic force on the bar magnet

    Assalamu'alaikum
    nice blog :)
    i want to asky you, why the form oh iron powder around magnet is circular?

    Good Job to you...

    We have seen that a charged object produces an electric field E at all points in space. In a similar manner, a bar magnet is a source of a magnetic field B . This can be readily demonstrated by moving a compass near the magnet. The compass needle will line up along the direction of the magnetic field produced by the magnet

    Notice that the bar magnet consists of two poles, which are designated as the north (N) and the south (S). Magnetic fields are strongest at the poles. The magnetic field lines leave from the north pole and enter the south pole. When holding two bar magnets close to each other, the like poles will repel each other while the opposite poles attract.

    Unlike electric charges which can be isolated, the two magnetic poles always come in a pair. When you break the bar magnet, two new bar magnets are obtained, each with a north pole and a south pole. In other words, magnetic “monopoles” do not exist in isolation, although they are of theoretical interest.

    wow WE O WE
    magnets are weird
    just like you
    but this is cool
    where i can get the iron powder
    keep the spirit of making article
    SEMANGAD..................!!!!!!

    mulinda,
    from the experiment we can get a magnet right? so Can we distinguish where is the nort poles and south poles?
    thanks
