What are the types of magnets?
Ferro-magnets, permanent magnets, temporary magnets, and electromagnets. Ferro-magnets are magnets that are magnetic at a higher temperature than room temperature. do not quote me on that. permanent magnets are magnets that are always magnets, they are the kinds you use a lot. Temporary magnets are things that are magnetic in an extrenal magnetic field. Last but not least, electromagnets. Electromagnets are coils of wire around a cobalt, nickel, or iron. When ou run electricity through the wire, the core and wire become magnetic.
What kind of magnets do magnetic levitation trains use?
Electromagnets
What are the 4 magnetic materials?
the 4 magnetic materials are iron, steel, copper and nickel
What has the author T B Montgomery written?
T. B. Montgomery has written: 'Design of magnets and electromagnets' -- subject(s): Magnetism, Electromagnets, Magnets, Magnetic devices
What is the different electromagnets and permanent magnet?
Electromagnets are non permanent magnets. They got magnetic field because of applied electric field. They lost their magnetic field which was around that, when the applied electric field is stopped. permanent magnets have magnetic property always with it. Permanent magnetic property loses when we heat the material. It cannot be regained once again. But electromagnets are capable of regaining its magnetic properties.
What is affected by electromagnets?
Other magnets, as well as magnetic substances such as iron, in which magnetism is induced by the external magnetic field.
Why are there magnetic force in magnets?
Magnets have magnetic force in them, obviously, to attract or repel magnetic materials. The materials could not be attracted without the magnetic force because the magnet forces the magnetic material towards it.
Permanent magnets and electromagnets both hold their magnetism for a long period?
the answer is false Permanent magnets will hold their magnetism for a long period of time. Electromagnets will only remain magnetic as long as current is flowing through them.
What you is a magnetic material?
The materials attracted by magnets are called magenetic materials.
How do magnets behave?
Magnets are made from magnetic materials. These are metals that can be magnetised or will be attracted to a magnet. Most materials are not magnetic, but iron, cobalt and nickelare magnetic. Steel is mostly iron, so steel is magnetic too.
Are electromagnets used in cameras?
Camera magnets are actually electromagnets; the magnetic field on an electromagnet is only there when you need it. They work like magnets everywhere else do; they are used in place of springs.
Is planet made of magnets?
no its made of magnetic materials
