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.
A permanent magnet has magnetic properties because?
The magnetic domains are aligned
Define permanant magnet?
(n.) a magnet that retains its magnetism after being removed from an external magnetic field
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.
Groups of atoms with aligned magnetic poles are called magnetic what?
Within a magnet, the separate poles are composed of domains, regions where the individual atoms are aligned with parallel magnetic moments.

A piece of magnetic material that retains its magnetic properties after it is removed from a magnetic field?
That's a "permanent" magnet.
A material that holds its magnetic properties without losing them is a?
permanent magnet .
Objects that keep their magnetic properties for a long time?
A permanent magnet (in contrast to an electromagnet).
Define permanant magnet?
(n.) a magnet that retains its magnetism after being removed from an external magnetic field
What is the difference between a permanent magnet and a temporary magnet?
Temporary magnet: good example is an electromagnet. It maintains magnetic attraction only so long as an electric current surrounds it. Permanent magnet: most common. Example: bar magnet. Will maintain magnetic properties for quite a while, although they can be eventually demagnetized.
Type of magnet?
There are two main types of magnet - Permanent and electromagnet. Electromagnets are usually in the form of a coil wound around an iron core. When current passes through the coil the core becomes magnetic. A permanent magnet is made of a material that naturally exhibits magnetic properties.
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.
Can a permanent magnet and a temporary magnet be made from the same magnetic material?
no they can not.
How does a permanent magnet stay magnetic?
Inertia. A system will not change it's properties until an external force is applied. Permanent magnets DO decrease in strength by being used as they are subjected to external magnetic fields that oppose them. How much a permanent magnet will be affected by the external field depends on it's Hysteresis loop characteristics.
What is the difference between magnet and magnetic and magnatism?
A magnet is an object that is magnetic if it displays magnetic properties. Think of it like this; If bar magnet attracts a piece of metal towards it, it is using magnetism (fluxuations in electric current) and therefore the magnet can be said to have magnetic properties.
