What can you use to show the magnetic field of a magnet for people to see?
Little bits of other magnet. Iron filings - the small pieces of metal will floow the magnetic field lines.
How can metal become a temporary magnet?
By putting metal piece in contact of other magnet or magnetic field.
Can magnets also repel metal?
No, magnets cannot repel metal. To repel something with a magnet it would have to have a magnetic field.
How does the earth's magnetic field function?
convection currents in the outer core (which is in liquid form) move the molten metal of the outer core around to create the magnetic field. The magnetic field then blocks certain rays from the sun.
What kind of electrical sensor does a metal detector use?
One which responds to the disruption of a magnetic field.
Are the magnetic lines force of a bar magnets strongest at the end of the magnet or in the middle?
That is where the field lines originate and therefore where they are thickest. The thicker the field lines, the stronger the field. To see the magnetic field lines, cover your magnet with a piece of paper and spread metal fillings over it.

What is used to represent magnetic field lines on a diagram?
Curved lines are used to represent magnetic field lines. The closer together they are, the stronger the magnetic field. Arrows are added to show the direction a north pole would move if placed at that point.
What is the procedure to draw magnetic field lines?
If it is a small magnet, like one that you can hold in your hand, place the magnet on a flat surface, put a white sheet of paper over it, take iron shavings or shavings from a magnetic metal, and sprinkle them on the paper. Gently shake the paper if you have to. You should start to see lines from where the magnetic fields attracted the metal.
Where does the earth's magnetic field get its power from?
earths magnetic field is generated by the circulation of liquid metal.
What happens when metal filings are dropped on a sheet of paper that has a bar magnet beneath the paper?
A bar magnet creates an invisible magnetic field around it, and magnetic metals such as iron are attracted to the magnet. Any metal structure is then included in the magnetic field lines. For iron filings on the sheet of paper, they will group into clusters near the poles, and also form an oval pattern along the length of the magnet, representing the magnetic field lines. The field is bulged outward nearest the center of the magnet's length. This displays the approximate two-dimensional shape of the three-dimensional magnetic field. For a picture, see the related link.
What are sources make up the earths magnetic field?
The earth's magnetic field is caused by convection currents in our core. The core is made out of iron, which is a magnetic metal.
What does a magnetic field around a planet indicate?
That it has a metal core.
Which metal is stop the magnetic field no effect in other side?
nothing can disrupt a magnetic feild
Why do scientists believethat the inner core is the source of earth's magnetic field?
The core is a dense chunck of metal that influence the earths magnetic field.
Does the moon have an active magnetic field?
To have an active magnetic field you must have a reasonably fast rotation speed, and a molten metal core. The earths moon has neither of these, so the answer is No, the moon doesn't have a magnetic field of any kind.
What are the causes of magnetic fields?
Earth's magnetic field is produced by the dynamo effectin the liquid metal outer core.
