What is true about permanent magnets?
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.
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.
What types of magnets are harder to magnetize but retain magnetism much longer?
permanent magnets
Are paperclips 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.
What are the differences between electromagnets and permanent magnets, and how do electromagnets differ from permanent magnets?
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.
Are electromagnetic magnets permanent?
No, electromagnets are not permanent.
What is true of permanent magnets?
Permanent magnets retain their magnetism without the need for an external magnetic field. They are typically made of materials such as iron, cobalt, and nickel, and have north and south poles that attract or repel each other. Their strength and duration of magnetism depend on factors like material composition and manufacturing process.
What type of magnets are harder to magnets but retains magnetism much longer?
permanent magnets
A permanent magnet can affect?
A permanent magnet can affect magnets and electromagnets.
Where can I find permanent magnets?
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.
Does water effect permanent magnets?
not really. is depends on what kind of magnets they are.
How do magnets work naturally?
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.
