What are two ways to make a unmagnetized ferromagnetic material?
Heating the ferromagnetic material above its Curie temperature so that it loses its magnetic properties. Applying an alternating magnetic field that repeatedly changes direction, causing the magnetic domains within the material to become disordered and cancel out each other's magnetic effects.
Does a magnet attract a key?
It depends on the material the key is made of. If the key is made of a ferromagnetic material, such as iron, then yes, a magnet will attract it. If the key is made of a non-magnetic material, such as aluminum or brass, then the magnet will not attract it.
Will magnet stick to silver plate?
Probably not. You need a ferromagnetic material for a magnet to stick. There are basically three elements that are ferromagnetic: Cobalt [Co]; Nickel [Ni]; & Iron [Fe] (and some esoteric ones too). If the metal alloy that has been plated with silver to make the "silver plate" has enough of these then a magnet will stick, of these, only Nickel is commonly a component of alloys that are plated but often not in concentrations that are sufficient to make it obviously magnetic.
Is silver attracted to a magnet?
Sterling silver is a non-ferrous metal alloy, so a magnet will not stick to it. Many metals, however, are non-ferrous, so just because a magnet doesn't stick to a particular metal doesn't make it sterling silver.
How can you use a solenoid to make a temporal magnet?
Passing it through a coil that has a DC current through it. The DC current creates a field which allows the realignment of electrons in the solenoid, allowing it to have temporary magnetic properties. Passing an AC current through the coil would demagnetize the solenoid.
Is cobalt a hard or a soft magnetic material?
Cobalt is ferromagnetic, but considerably less so than iron. Alloys of cobalt such as aluminium, nickel, cobalt and iron, known as Alnico, and of samarium and cobalt (samarium-cobalt magnet) are commonly used to make high quality permanent magnets.
How do you make a temporary magnet?
To make a temporary magnet, you can rub a piece of iron or steel with a permanent magnet. This process aligns the magnetic domains in the material, creating a temporary magnetic field. To enhance the temporary magnetism, you can increase the number of times you rub the material with the permanent magnet.
Does iron make use of magnet to work?
Yes, iron is a ferromagnetic material, meaning it can be magnetized and exhibit magnetic properties. When iron is brought into contact with a magnetic field, its atoms align to create a magnetic field, allowing it to be attracted to magnets and exhibit magnetic behavior.
How can you make a magnet stick to aluminum?
You cannot make a magnet stick directly to aluminum because aluminum is not magnetic. However, you can make a magnet stick to aluminum by placing a magnetic material, such as iron, in between the magnet and the aluminum surface.
Will a magnet still be a magnet if it is melted?
A magnet is produced by aligning the magnetic domains in a material to point in the same direction. When heated, the magnet loses its magnetism as the molecular motion, which is caused by heating, destroys the alignment of the magnetic domains. Ferromagnetic materials also lose its magnetism after being melted. However, when the magnet is being hammered whilst cooling in a magnetic field, the melted magnet would gain its magnetism again.
