When a magnet becomes demagnetized whats really happening is the arrangement of the domains is getting out of particular arrangement.
When electrons are randomly arranged they cancel each others field and overall effect is zero.
When a stronger magnetic field is applied to the object, its magnetic effect can be restored.
In an unmagnetized material, the electron spin creates magnetic fields, but they ar randomly oriented so the net magnetic field of the substance is zero. When the substance is magnetized, the electron spins are re-oriented so that the magnetic fields produces by the spins are parallel, thereby reinforcing each other. If the material is ferromagnetic, then the orientations will remain and the material will have a magnetic field of it's own.
yes it is possible to make a magnet from iron because it is magnetic and magnetic things can be turned into magnets.
Magneto. magneto is the god of magnets, who created the Field around the earth to protect those who inhabited it. but in doing this, he turned mortal and inhabited the body of a human, who is now today still known as magneto (see x-men) you idiot
A magnet is by definition magnetic. What was a magnet may now be simply a piece of steel or iron, since losing its magnetism makes it not a magnet anymore. An electromagnet is only magnetic when it has current running through it, and is not magnetic when turned off.
This is fusion not fission. In stars like our sun, hydrogen is turned into helium
Steel is manufactured. Iron ore is mined and turned into iron. Then the iron is mixed with other metals and materials to get steel.
Electromagnet which uses electric current can be turned on and off.
Permanent magnets can be turned off.
An electromagnet can be turned on and off, with an electric current and a magnet can not turn off
Metals that are attracted by magnets or that can be turned into magnets are as follows: 1-iron 2-cobalt 3-nickel 4-steel (a compound not an element)
An electric field causes electrons to flow when a switch is turned on.
An electric field causes electrons to flow when a switch is turned on.
An electric field causes electrons to flow when a switch is turned on.
Magnets that are turned on by passing an electric current through them, and turned off by not allowing an electric current through them.
Because they can be turned off and on again(unlike permanent magnets) they can pick up steel and other magnetic materials that can be recyled and more them to seperate places. Therefore seperating the rubbish.
The wind turns a blade connected to a transmission, which ensures a consistent speed. The transmission is connected to a generator which produces electricity by magnets being turned around a wire, making electrons flow and producing electricity
cobalt can be turned into many things from magnets to jewlery to blue glass
Electromagnets can be turned off and off
