Which magnetic material can retain permanent magnetization?
False permanent magnets can but electromagnets need a running current A+
Objects that keep their magnetic properties for a long time?
A permanent magnet (in contrast to an electromagnet).
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.
Can Permanent magnets be turned on and off?
Electromagnet which uses electric current can be turned on and off.
What are metals that are attracted to magnets or made into magnets called?
Unpaired electons (which is to say, electrons not paired with another electron of opposite spin).
What is true of permanent magnets?
Permanent magnets contain a current-carrying wire.
What do permanent magnets contain?
Permanent magnets contain magnetic atoms (almost always iron) whose magnetic poles are all (or mostly) aligned in the same direction.
What do all electric motors contain?
"permanent and temporary magnets"
Does an electric egg beater contain magnets?
Yes, an electric egg beater will have some kind of magnets in it. These may be permanent magnets, or may be electromagnets, but the motor in the appliance will have to have some kind of magnets in it to operate on electricity.
Are magnets living things?
No, most permanent magnets are made of Iron or NIckel compounds. They are inorganic metals or metallic compounds.
What types of magnets are harder to magnetize but retain magnetism much longer?
permanent magnets
Are permanent magnets only attracted to other permanent magnets?
No, they are attracted to: Other permanent magnets Solenoids Iron Wires with current running through them
Are electromagnetic magnets permanent?
No, electromagnets are not permanent.
How are permanent magnets bad?
Permanent magnets aren't bad. period. I do not know where you heard that but whatevs..
Where can I find permanent magnets?
Permanent magnets can be purchased from sites such as Magnet Sales and PML India. A permanent magnet is more resistant to factors that would demagnetise it than regular magnets.
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 do not quote me on that.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 is the difference between a permanent and non permanent magnet?
Permanent magnets are bar magnets or horse shoe magnets which has magnetism at all times. But non permanent also known as temporary magnets are usually electromagnets which would have magnetism only when current flows through the coil that surrounds it.
