Will magnets lose it's power by rubbing?
Rubbing a magnet against another object can cause minor changes in its magnetic field, but it is unlikely to significantly weaken the magnet's overall strength. Magnets can lose their power over time due to various factors such as exposure to heat, strong external magnetic fields, or physical damage.
What is the attraction of a magnet for another object?
A magnet attracts another object due to its magnetic field, which is a force that pulls certain materials towards it. This attraction occurs because of the alignment and movement of the magnetic domains within the magnet and the object, creating a magnetic force between the two.
Why does iron become magnetised?
The magnet, in this case, will induce magnetism in the iron. The iron has lots of tiny areas that are magnetic, but normally point in random directions; placing a magnet nearby will allign those, and thus induce the magnetism.
Magnetism can sometimes be induced in an iron object by?
1.Stroking it with a magnet 2. Applying a current to a coil of wire wrapped around the iron
What is the difference between magnet and magnetic and magnatism?
A magnet is an object that is magnetic if it displays magnetic properties. Think of it like this; If bar magnet attracts a piece of metal towards it, it is using magnetism (fluxuations in electric current) and therefore the magnet can be said to have magnetic properties.
When you rub a magnet with metal what happens to the metal object?
When you rub a magnet with metal, the metal object becomes temporarily magnetized. This happens because the atoms in the metal align with the magnetic field of the magnet. However, once the magnet is removed, the metal object loses its magnetism.
How does the weight of a magnet affect its strength?
The weight of a magnet does not directly affect its strength. The strength of a magnet is determined by its magnetic material, shape, and how it is magnetized. A heavier magnet may have more material in it, which could potentially make it stronger if the material used has high magnetic properties.

How do you Turn a non magnetized object into a magnet?
You can turn a non-magnetized object into a magnet by rubbing it with a magnet in the same direction multiple times. This process aligns the magnetic domains within the object, causing it to become magnetized.
Is magnetism a mineral?
A magnet is a man-made object, made from minerals that are magnetic or iron that has been magnetized.
What are 3 ways to magnetize an object?
Rubbing a magnet against the object in a single direction to align its magnetic domains. Applying an electric current to the object to induce magnetism through electromagnetism. Exposing the object to a strong magnetic field to align its magnetic domains.
What is the attraction of a magnet for another object?
A magnet attracts another object due to its magnetic field, which is a force that pulls certain materials towards it. This attraction occurs because of the alignment and movement of the magnetic domains within the magnet and the object, creating a magnetic force between the two.
How do you make a temporary magnet without electricity?
You can make a temporary magnet by rubbing a piece of iron or steel with a permanent magnet. This aligns the domains in the material, creating a magnetic field. However, this magnetism will fade over time as the domains become disorganized again.

What is induced magnetism?
In the simplest terms, Induced Magnetism is the magnetism of an object as a result of an external influence. Typically, the external influence is a magnetic field due to another object. (One also hears the term transient magnetism applied to the same phenomenon. To be considered transient, the magnetism must disappear when the external influence disappears, but to be "induced" it just has to appear.) Though this is a technical term, it has a meaning that is the normal meaning of "induced," as in "caused by." This is to be contrasted with other modifiers, like "permanent magnetism" or "remnant magnetism" or "spontaneous magnetism" which are all still magnetism of an object but with a modifier further describing the magnetic state. If one is being more technical, then in scientific circles the term "induced magnetism" usually refers the situation where an object acquires a magnetic field as a result of it being in some external magnetic field even though it is not normally a magnetized material. One see this all the time. If you bring a permanent magnet near a collection of paperclips, then the paperclips all attach to one another and to the permanent magnet. Each paperclip has become, temporarily, a magnet. If the permanent magnet is removed, the paperclips no longer attach to one another. The magnetic properties of the paperclips were "induced" and not a permanent characteristic. More technicalities can be present with this term, because magnetism in an object can be induced in other ways than the application of a magnetic field. In the absence of such technical considerations, it is safe to assume that the term "induced magnetism" just means a temporary state of magnetization of an object induced by an external magnetic field provided by a permanent magnet or an electromagnet.
