Permanent magnets don't get energy from anywhere. The nature of the atoms a natural magnet is made of allow for the free exchange of electrons with other objects that also have free electrons. Energy is conserved in the system, not used and so a natural magnet doesn't need power to operate.
What else can I help you with?
For a permanent magnet where is the energy associated to the magnetic field of the magnet stored?
The energy associated with the magnetic field of a permanent magnet is stored in the magnetic dipoles of the material making up the magnet. When the magnet is magnetized, these dipoles align in a way that stores energy within the material. This stored energy can be released when the magnet interacts with other magnetic materials or experiences mechanical forces.
Is the magnet in a compass a permanent magnet or electronic?
A. Compasses typically use a permanent magnet.
Is a needle in a compass a permanent magnet?
Yes, it is a permanent magnet.
Is magnetite a temporary magnet?
No, it's a permanent magnet. It consists of an iron oxide, and iron is a permanent magnet.
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.
How can a magnet be temporarily magnetized when attached to a permanent magnet?
When a magnet is attached to a permanent magnet, it can become temporarily magnetized by aligning its magnetic domains with the strong magnetic field of the permanent magnet. This alignment causes the magnet to exhibit magnetic properties for a short period of time.
Is the magnet in a compass a permanent or electromagnet?
The magnet in a compass is a permanent magnet. It retains its magnetism without the need for an external electrical current.
Is a permanent magnet called a hard magnet or a electromagnet?
Perminant magnet
Is magnetite a magnet?
No, it's a permanent magnet. It consists of an iron oxide, and iron is a permanent magnet.
Why is a permanent magnet necessary for an electric motor to function effectively?
A permanent magnet is necessary for an electric motor to function effectively because it creates a magnetic field that interacts with the electric current flowing through the motor's coils, causing the motor to generate rotational motion. This interaction between the magnetic field of the permanent magnet and the electric current is essential for the motor to convert electrical energy into mechanical energy efficiently.
What is a permanent magnet motor?
A motor with permanent magnets rather than field coilsA:A non-functional contraption often peddled as a free-energy generator.
Is the magnet in a compass a permanent magnet or a electromagnet?
It is a permanent magnet. Electromagnets(as the name suggests) requires an electric source to become a magnet, when the power source is turned off it will not function as a magnet.
