Permanent magnets contain a current-carrying wire.
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 do not quote me on that.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.

Yes, permanent magnets are commonly used in doorbells to create the magnetic field needed for the electromechanical mechanism to operate. The magnets help in generating sound by attracting and repelling the internal components of the doorbell to produce the ringing noise.
The stator of an electric motor contains coils of wire that generate a magnetic field when an electric current passes through them. This magnetic field interacts with the permanent magnets on the rotor, causing them to repel each other and create motion in the motor.
A magnet always has two poles.They have a magnetic field.Electromagnets can be made much stronger than permanent magnets.A magnet always has two poles.
They are difficult to magnetize,
Permanent magnets have their own magnetic field that does not require external electrical current to maintain. They can attract or repel other magnetic materials without losing their magnetic properties. Common materials used for permanent magnets include iron, nickel, and cobalt.

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.
No, paperclips are not permanent magnets. They can temporarily exhibit magnetic properties when in the presence of a magnetic field, but they do not retain magnetism like permanent magnets do.
No, electromagnets are not permanent.
Electromagnets and permanent magnets differ in how they are created and their magnetic properties. Electromagnets are temporary magnets created by passing an electric current through a coil of wire, while permanent magnets are naturally occurring magnets with a fixed magnetic field. Electromagnets can be turned on and off by controlling the electric current, while permanent magnets always have a magnetic field.

A permanent magnet can affect magnets and electromagnets.
Permanent magnets can be found in stores that sell hardware or industrial supplies, as well as online retailers. Specialized magnet stores or suppliers may also carry a wide variety of permanent magnets for different uses.
not really. is depends on what kind of magnets they are.
Natural magnets, such as lodestones, have a permanent and persistence magnetic field. These permanent magnets can also temporarily magnetize material such as iron, nickel, and cobalt.
