What are the different types of magnet?
bar magnet, horse shoe magnet,ball ended magnet and cylindrical magnet.I recomend doing the iron shavings and bar magnet experiment.x.x TRY IT .There are 3 types o magnets parmanent, temporary, and electromagnets.you can also use water andblue food colloring to create a magnetic field.Bar Magnet, horseshoe magnet etc
Where can you get a magnet?
For a new super strong magnet that has just been developed called rare earth neodymium magnets, there is a website in the related links below. I looked at it earlier and the prices were quite reasonable. But search the web to compare prices. I personally have a pile of magnets that I have scavenged over the years from mechanical devices. The magnetrons in microwave ovens in particular have two very strong relatively large magnets. Small electrical motors usually have permanent magnets in them. Speakers do as well.
What is the role of permanent magnets in a speaker?
The electromagnet is positioned in a constant magnetic field created by a permanent magnet. These two magnets -- the electromagnet and the permanent magnet -- interact with each other as any two magnets do. The positive end of the electromagnet is attracted to the negative pole of the permanent magnetic field, and the negative pole of the electromagnet is repelled by the permanent magnet's negative pole. When the electromagnet's polar orientation switches, so does the direction of repulsion and attraction. In this way, the alternating current constantly reverses the magnetic forces between the voice coil and the permanent magnet. This pushes the coil back and forth rapidly, like a piston.
What does it mean when two magnets attract?
When two magnets attract, it means that the opposite poles of the magnets are facing each other. This causes a magnetic force to pull the two magnets together. The attraction occurs due to the alignment of the magnetic fields surrounding the magnets.
What is the name of the force between two magnets?
The force between two magnets is called magnetic force.
What household objects have magnets in?
Two household objects that have magnets are: fridge magnets, and sizzlers
What are the eleven types of magnets?
There are two fundamental types of magnets, permanent and electromagnet. Both of these may be presented in numerous forms, and there seems no merit in considering any particular eleven.
What is a true statement about the magnetic field between two magnets?
The south pole of one magnet is attracted to the north pole of the other magnet.

What are statement that are true of magnets?
A magnet always has two poles.They have a magnetic field.Electromagnets can be made much stronger than permanent magnets.A magnet always has two poles.
If you force the like poles of two permanent magnets to stay together will they eventually stop repelling each other?
i dontd think so

What type of train uses magnets?
The maglev train floats over its track using an electromagnet. Maglev trains have managed speeds in excess of 370mph. A model of the maglev train uses two permanent magnets to get the model to float over the track.Describe how the magnets must be arranged to get the model Maglev Train to float.
