Stanley Demonstrates Magnetism With Several Types of Magnets

Bar Magnet

Place the bar magnet on a table.
Put a sheet of glass or plastic over the magnet.
Sprinkle the iron filings over the sheet evenly.
On a separate paper, sketch the magnet. Show the lines made by the iron filings.

Horseshoe Magnet

Place a horseshoe magnet on the table.
Put a sheet of glass or plastic over the magnet.
Sprinkle the iron filings over the sheet.
On a separate paper, sketch the magnet. Show the lines made by the iron filings.

N Pole to N Pole

Place two bar magnets N pole to N pole with an inch between them.
Put a piece of glass or plastic over the magnets.
Sprinkle the iron filings over the glass or plastic.
On a separate paper sketch the magnets. Show the lines made by the iron filings.

N Pole to S Pole

Turn one of the bar magnets around so the magnets are N pole to S pole with an inch between.
Sprinkle the iron filings over the glass or plastic.
On a separate paper sketch the magnets. Show the lines made by the iron filings.

From the information you have observed, determine the following:

What rule of magnetism is illustrated by the lines of the iron filings in Step 12?

What rule of magnetism is illustrated by the lines of the iron filings in Step 15?

Why was glass or plastic used to separate the filings from the magnets in the experiments?

Did the glass or plastic stop the passage of the magnetic lines of force?

Did the iron filings almost or completely bridge the open end of the horseshoe magnet?

From the statement number 12: "On a separate paper sketch the magnets. Show the lines made by the iron filings. N Pole to S Pole"

The law of magnetism illustrated here is that in magnetism, opposites attract.

Thus the pattern formed by the iron filings is unique from the pattern which will be formed after step 15: "On a separate paper sketch the magnets. Show the lines made by the iron filings. S pole to S pole"

The law of magnetism illustrated in step 15 is like poles repel each other, resulting to the unique patterns formed.

Answer:

The magnetism is either created inside a given element by passing some number of charges,Q across it or it is due to the interaction with a permanent magnet. The magnet consists the characteristics of having an optimum amount of energy (P.E inside it) inside it. As, the energy lines are either directed outwards from the north pole of the magnet, the south pole of the magnet consumes or absorbs the magnetic rays(energy lines) originated from the north pole of the magnet.

Answer(1): The right hand rule of magnetism is illustrated in the 12 point of the question.As the right hand rule says that there will be a net amount of magnetic field around the conductor or any current carrying element in a specific direction. Now, the current carrying direction of the wire is in perpendicular direction to that of the magnetic field created.

Answer(2): Point No.15 of the given question provides us the information regarding the idea of left hand rule of magnetism. As, due to the contact between the magnetic fields.

The fillings are separated from the magnets in the given experiment due to the fact there is a source for covering up the particles from getting too much exposed to the magnetic field. But, they are not able to stop the magnetic line of force,F from not penetrating its surface.
The iron fillings are present there to have a complete bridged form of connections between itself and the horseshoe magnet.As the horseshoe magnet and the iron fillings are placed in a specified form of orientation inside the given space or region of interaction.
