Plotting Magnetic Field Lines

Рет қаралды 316,061

A simple experiment demonstrating how iron filings may be used to plot field lines around:
A single magnet
Two magnets (repelling)
Two magnetic (attracting)
A current carrying wire
A current carrying solenoid (a long coil)
The basic technique is:
Cover the magnets with paper (or place paper in the area you will be scattering the filings)
Gently shake a few iron filings on to the paper.
Tap the paper gently to help the iron filings settle into a pattern.
The field line for the current carrying wire are very faint and difficult to see. This is because the field that is produced is very weak. If you look carefully, though, you may be able to make out some concentric circles going around the wire.

Magnetic field lines may actually be circles. Consider a bar magnet. The two poles of the magnet can be considered as two points and the length of the bar magnet can be represented by a segment joining those two points. Now construct a perpendicular bisector of this segment. Then for every point in this perpendicular bisector, construct circles whose radii are equal to the distance of the given point from the endpoints of the segment. You will create multiple circles passing through both the endpoints. If you construct enough circles by hand or software (recommended), you will see a pattern start to emerge that looks very much like the pattern exhibited by the magnetic field lines of a bar magnet. Try it. While I cannot be sure that it is the exact pattern exhibited by the bar magnet, it looks a lot like it.

why are there "field lines" at all? why not a homogenous "sheet" of filings? do they really show lines of force when they can be freely moved? and why, if one line of filings is moved, do adjacent lines tend to also move and maintain a certain distance? wouldnt one say that there is a force at right angles to the so called "line of force", spreading them apart? maybe the "line of force" is an illusion, a mistake on faradays part? also consider with the bar magnet... it is only a slice at some chord of the field. it isnt a slice through the center of the field like the solenoid shows. makes me wonder what "field" the solenoid produces if the sheet is placed alongside it as well rather than "through" it... something about the field of a bar magnet and the field of a solenoid is different...

A nice suggestion, but the current I was using doesn’t create a strong enough field to pull the filings into line. The magnetic field produced by a wire (or a loose coil, if it doesn’t have an iron core) is actually quite weak.

Those empty positions where irons are not arranged, does that mean that there is no magnetic field?

@QuantumBoffin 2 жыл бұрын

Great question! The magnetic field is actually continuous and is present (and just as strong) between the field lines. The reason new filings don’t fill the gaps between the lines is because they are attracted to the other iron filings (which have been magnetised).

Bro this experiment is explaining magnetic field is discrete not continuous. But i want to know how the direction of magnetic field is determined. I mean magnetic field moves out of north pole and moves in to the south pole

@QuantumBoffin 2 жыл бұрын

In order to do that, you will need to use a plotting compass: place it on a field line and it will point in the direction of the field. I have another video that demonstrates this.

@QuantumBoffin 2 жыл бұрын

You need a very strong magnet (or electromagnet) for that to work, as it takes a bit of force to make the iron filings move, and there is a tendency for them just to clump together.

@firdousfatima7120 2 жыл бұрын

@@QuantumBoffin yes absolutely also i have one question !! how does the iron filling form 'lines' and not clump together bcuz when we use a magnet the iron stuff around it gets attracted towards it and sticks to it and this lines are quite away from this ?! how is this possible like do we need an actual magnet for stuff to stick to it or magnetic fields can also make stuff stick to itself?

@QuantumBoffin 2 жыл бұрын

Nice question! Most people don’t think of asking this and most teachers don’t know the answer (possibly because it’s never occurred to them before). The reason for the lines is because when the first iron filing is sprinkled it becomes magnetised: one end becomes a North Pole and the other a south. Other iron filings will then stick to the ends of the first iron filing, and also becomes magnetised. This process repeats, causing the filings to form a chain: our field line.

@jnhrtmn 3 ай бұрын

The field "lines" don't exist until to put the iron powder there. Notice that the lines created by the iron change spacing when you tap on the page. The mass in the iron channels the magnetic field through itself and concentrates it, and this affects other iron mass in doing the same nearby. Each time you tap the page, they consolidate, and the spacing changes. So many people watch this and get programmed into thinking that the lines come first, but they don't.
