What type of magnet can only attract materials when it is touching another magnet?
Metals not magnetic, but permeable will become magnets when near or touching a permanent magnet. You can stroke some metals in the same direction repeatedly on a magnet and make it a magnet.
What metals do magnets only attract?
Ferrous metals, such as: Iron (Fe) Cobalt (Co) and some alloys respond to magnetism. Aluminum responds to electromagnetic eddy currents.
Is not a permanent magnet?
An electromagnet is a magnet while an electric current is running through the coil. Turn off the current and it is no longer magnetised, and is, therefore, not a permanent magnet.
What is the difference between permanent pole and temporary pole?
a Temporary Magnet lose its magnetism quickly, a Permanent Magnet is hard and it keeps it magnetism
Why do magnets make a N and S pole when you break a magnet?
Because in a permanent magnet, there is always a magnetic field, if the permanent magnet is broken, and didn't have a S and a N, then magnetism would cease to exsist.
What type of magnet can only attract materials when it is touching another magnet?
Metals not magnetic, but permeable will become magnets when near or touching a permanent magnet. You can stroke some metals in the same direction repeatedly on a magnet and make it a magnet.
Is the magnet in a compass a permanent magnet or electronic?
A. Compasses typically use a permanent magnet.
What are likely to be affected by a magnet?
Both permanent magnets and electromagnets. -Apex
Is magnetite a magnet?
No, it's a permanent magnet. It consists of an iron oxide, and iron is a permanent magnet.
Is a needle in a compass a permanent magnet?
Yes, it is a permanent magnet.
What metals do magnets only attract?
Ferrous metals, such as: Iron (Fe) Cobalt (Co) and some alloys respond to magnetism. Aluminum responds to electromagnetic eddy currents.
Is magnetite a temporary magnet?
No, it's a permanent magnet. It consists of an iron oxide, and iron is a permanent magnet.
What is ferromagnitism?
ferromagnitisation is the property of certain metals to form permannent magnets. these metals are attracted by magnet, this type of magnitisation is the strongest.
What kinds of irons attract to a permanent magnet?
What, precisely, are these "kinds of irons" you speak of? If you meant "what kinds of metals" ... the ferromagnetic ones, of course.
What distinguishes a permanent magnet from a temporary magnet?
Permanent magnets do not lose their magnetic ability. Temporary magnets, however, gain magnetic properties when they are touched or moved by a permanent magnet. The properties of a temporary magnet dissipates over time after the permanent magnet is removed.
Is the magnet in a compass a permanent magnetic or an electromagnet?
PermanentThere is no source of current in a compass, therefore the magnet is a permanent magnet.
Is a Refrigerator magnet a Permanent magnet?
yes
