Iron filings are small shavings of a ferromagnetic material.
Magnetic waves iron filings marble.
An electromagnetic wave is an oscillating electric field that creates an oscillating magnetic field that creates an oscillating electric field.
In physics magnetism is a force that can attract pull closer or repel push away objects that have a magnetic material like iron inside them magnetic objects in simpler words it is a property of certain substances which pull closer or repel other.
Most waves need some type of medium to move through.

Magnetic lines of force of a bar magnet shown by iron fe filings on paper.
We can t normally see magnetic fields but if you sprinkle iron filings tiny bits shaved off an iron bar with a file onto a piece of paper and hold it above the magnets you can see the field underneath.
The strength of repulsion and attraction depends on the strength of the magnetic poles.
Iron filings 1 pound package 4 4 out of 5 stars 188.
Ms ps2 5 students can use the sealed iron filings to conduct an investigation and evaluate the experimental design to provide evidence that fields exist between objects exerting forces on each other even.
That being the case iron filings are an excellent way to display the magnetic field of one or multiple bar magnets.
Magnetism is a class of physical phenomena that are mediated by magnetic fields.
Sprinkling iron filings on a sheet of paper and bringing a magnet up close to the underside of the paper we can see that the filings line up along the lines of force of the magnetic field thus showing its contours.
An object capable of attracting material such as iron or steel by magnetic force is called a magnet or bar magnet.
Place a magnet under a piece of paper and shake the filings on top.
Place your magnet in a plastic bag to avoid the mess of cleaning iron filings off your magnet.

Electric currents and the magnetic moments of elementary particles give rise to a magnetic field which acts on other currents and magnetic moments.
Ferromagnetic for the purposes of this page at least means that they will align themselves with a magnetic field.
The magnetic field between the opposite poles of two bar magnets that strongly attract one another.
Experiment with magnetic fields using iron filings.
The filings will reveal the magnetic field lines.
Students can use the sealed iron filings to ask questions about data to determine the factors that affect the strength of magnetic forces.
The property of attracting objects by magnetic force is known as magnetism.
