What causes the strength of a magnet?
The strength of a magnet is determined by the alignment and number of its magnetic domains, which are tiny atomic magnets within the material. Factors such as the material used, its atomic structure, and the presence of an external magnetic field can all affect the strength of a magnet.
How can you show that a given bar is a magnet?
The following two methods are really the same idea:1). Test against a known magnet. Observe whether there is an attraction or repulsion between them.2). Hang the bar by a string from its mid-point. Observe whether it shows a tendency to align itself in a preferred direction.Another method:3). Observe whether the bar picks up paper clips. ---- If you have two bars and are told that one of them is a magnet but the other is not, and you are not allowed to use any other metal, string, etc. to determine which is which, see which one is attracted to the middle of the other bar. That one's the magnet.
Why a fixed magnet attract a iornic objects eventhough magneticfield doesn't do any work?
Iron has a very high permeability. So it lets maximum number of Magnetic lines of force to pass through it. The closer is the ironic conductor to the magnet, more is the number of lines of force passing through the ironic object. That is why the magnet attracts the ironic object.
How can you break a magnet with out breaking in in half?
Cutting a magnet in half can be done in a number of ways. A hack saw might work well (but the cuttings will stick to the magnet and the saw blade). Some magnets can actually be broken in half. But that leaves a "rough" end and is imprecise.
How many atoms are in a magnet?
Even a single atom (if it is the right kind of atom) can generate a magnetic field, so there can be any number of atoms in a magnet, from one onwards to very large numbers, such as 1025.
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.

How magnetic field can be strengthened?
A magnetic field can be strengthened by increasing the current flowing through a conductor, increasing the number of turns in a coil, using a material with higher magnetic permeability, or reducing the distance between the magnet and the object. Additionally, aligning the magnetic domains within a material can also strengthen its overall magnetic field.
What is a magnet and how does it work?
At the most fundamental level, all magnets are caused by moving electrons.In an electromagnet, there is an electric current flowing through a wire coil.In permanent magnets, a number of magnetic domains form, in which some adjacent atoms have their electrons spinning in synchrony.This is not common, but occurs in some materials due to the geometry of the crystal structure.The magnetic field of a magnet diminishes in strength the further away it becomes.
Which magnet is the strongest?
The strongest magnet contains neodymium a rare earth metal with atomic number of 60.

The number of lines of force in a magnetic field depends on the what of the magnet?
It depends on the strength of the magnet.
How can I increase the strength of a magnet?
To increase the strength of a magnet, you can do the following: Increase the number of turns in the coil of wire around the magnet. Use a stronger magnetic material for the magnet. Increase the current flowing through the coil of wire. Increase the number of coils in the wire around the magnet. Keep the magnet in a strong magnetic field when not in use.
The number of lines of force in a magnetic field depends on the blank of the magnet?
strength, the number of lines represents how strong the magnet is, this is also sometimes shown by the thickness of the lines.
The effect a magnet has on an atom is dependent on?
The effect a magnet has on an atom is dependent on the magnetic properties of the atom, such as its electron configuration and spin. Atoms with unpaired electrons are more likely to interact with a magnet and exhibit magnetic properties.
