The magnetic forces that cause the iron filings to align to the magnetic field are very weak and have trouble overcoming the forces of friction. When you tap the cardboard the filing jump up a bit and while they are in the air they are able to then rotate.

When a conductor is charged the charge moves to the outer surface of the conductor?

True. For instance in a wire, all of the charge is carried on the outside surface of the wire, and not down the center. Why?? Because when the electricity flows down the wire it causes alternating magnetic fields which cause alternating eddy currents within the wire. An eddy current is bascially an electromagnetic area of turbulence, and in this instance makes the flow of electrons easier on the outer edge of the wire. The higher the frequency that the electricity flows through the wire, the stronger the eddy currents and a thinner section of wire will carry the charge.


What areas in which electrons arrange themselves?

Electrons arrange themselves in specific energy levels or orbitals around the nucleus of an atom. These orbitals can be grouped into different electron shells. Additionally, electrons can also form bonds with other atoms to create molecules and compounds.


What happens to the density of rock as it cools?

As rock cools, its density increases. This is because cooling causes the atoms and molecules to arrange themselves in a more compact and ordered manner, leading to an increase in the density of the rock.


Why are snowflakes symmetrical?

Snowflakes are symmetrical because they form in a hexagonal shape due to the way water molecules arrange themselves when freezing. This symmetry is a result of the molecular structure of water and the conditions in which snowflakes form.


What is the most dense form of water?

Ice is the most dense form of water. When water freezes into ice, its molecules arrange in a way that makes ice denser than liquid water, which is why ice floats on water.

Why sprinkling iron filings in magnetic field on the cardboard around the wire they will align themselves in concentric circle?

When iron filings are sprinkled around a wire carrying an electric current, they align themselves along the magnetic field lines created by the current. The magnetic field generated by the current follows a circular pattern around the wire, and the magnetic properties of the iron filings cause them to respond to this field. As a result, the filings arrange themselves in concentric circles, visually demonstrating the shape and direction of the magnetic field around the wire. This phenomenon illustrates the relationship between electricity and magnetism, as described by Ampère's law.
