A permnent magnet generally made by soft iron. When we put a core of soft iron in a strong magnetic field, by induction it's made permanent magnet.
just superheat a peice of iron and put it in a precence of a strong magnetic feild and let it cool slowly
(be sure to heat it enough so it glows red hot)
What else can I help you with?
What are the uses for permanent magnets?
to make motors
Can you make a generator by mounting permanent magnets on a rotating shaft?
No.
What types of magnets are harder to magnetize but retain magnetism much longer?
permanent magnets
What is required to make permanent magnets?
Make sure they have got a negative and positive sides
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 is the element that is used to make permanent magnets and United States coins?
The element used to make permanent magnets and United States coins is iron. Permanent magnets are typically made from alloys of iron, while United States coins are primarily made of copper with a small amount of nickel (nickel-copper alloy).
Element used to make permanent magnets?
Iron, cobalt, and nickel are commonly used elements to make permanent magnets. These elements have magnetic properties that allow them to retain their magnetism over a long period of time.
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 metal is used in low melting alloys and magnets?
Several different metals can be used in magnets. Iron is perhaps the most common metal used in permanent magnets, but alloys such as Alnico (Aluminum, Nickel, and Cobalt) can also make very strong permanent magnets.
Can you make a running motor without using any energy using permanent magnets?
no
What type of magnets are harder to magnets but retains magnetism much longer?
permanent magnets
