Permanent
There is no source of current in a compass, therefore the magnet is a permanent magnet.

How is an electromagnet different from a refrigerator magnet?
A refrigerator magnet is magnetic because it is a "permanent" magnet. An electromagnet is a magnetic field caused by a current flowing through a wire.
What are different words that involve magnets?
Electromagnet Superconducting magnet Ferromagnetic Magnetic needle Magnetic compass magnetic field. Hydro magnet Gyro magnet
How is a permanentmagnet different from a electromagnet?
a permanent magnet is always magnetic as an electromagnet is only magnetic when it is wound around with wire and energised
How can you see the invisible magnetic field?
You can make magnetic field lines with a magnet. You an use a permanent magnet, or an electromagnet.
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.
What is the role of permanent magnets in a speaker?
The electromagnet is positioned in a constant magnetic field created by a permanent magnet. These two magnets -- the electromagnet and the permanent magnet -- interact with each other as any two magnets do. The positive end of the electromagnet is attracted to the negative pole of the permanent magnetic field, and the negative pole of the electromagnet is repelled by the permanent magnet's negative pole. When the electromagnet's polar orientation switches, so does the direction of repulsion and attraction. In this way, the alternating current constantly reverses the magnetic forces between the voice coil and the permanent magnet. This pushes the coil back and forth rapidly, like a piston.
Objects that keep their magnetic properties for a long time?
A permanent magnet (in contrast to an electromagnet).
What is true compasses?
They only point to the Magnetic NorthA compass is a permanent magnentA compass is a permanent magnet. A compass has both a south pole and a north pole. Compass magnets can be deflected by Earth's magnetic field or other permanent magnets.
Is a compass an electromagnet?
Usually it's a permanent magnet. You could use an electromagnet instead, but doing so is considerably harder from an engineering standpoint.
Is a compass a permanent magnet?
Compass needles are permanent magnets. in response to the Earth's magnetic field, the compass needle will point toward the geographic North Pole.
Match the object with its characteristic a mri permanent magnet b compass electromagnet c moon not magnetic?
ill give u the answer since i use wiki answers myself for tests and stuff *guilty* :)A mri is a electromagnetB compass is a permanent magnetC the moon is not magneticA.S apex :)
