What are the physical properties of a magnet?
Magnetism is a physical property because attracting something to a magnet does not change the substance (change of the composition) itself and doesn't involve chemical reactions. The magnetic state of a material depends on temperature (and other variables, such as pressure and the applied magnetic field), so a material may exhibit more than one form of magnetism depending on its temperature, etc. However, the magnetism doesn't change the substance itself.
How magnetic field is related with cathode rays in physics?
When a magnetic field is applied to a cathode ray, the cathode ray is deflected.
What metal cannot be magnetized?
Non-ferrous metals do not contain iron(Fe) and are therefore not ferromagnetic. Most common of these are copper, silver, aluminium, lead, magnesium, platinum and tungsten. Magnetic fields can produce reactions in all materials, however, and these fall into three general categories: # Ferromagnetic materials, such as iron, cobalt, and nickel, which have a large positive magnetic susceptibility, and are capable of being magnetised by weak magnetic fields. # Paramagnetic materials, such as aluminum, magnesium, and platinum, which have a positive magnetic susceptibility due to molecules or atoms in which there are unpaired electrons, resulting in a magnetic moment contributed to by the spin or orbital motion of the electron. # Diamagnetic materials, such as copper, lead, and silver, which have a negative magnetic susceptibility caused by the motion of electrons in atoms around the nuclei, as they change their orbits and velocities to produce a magnetic field that opposes an applied field.
What is the different electromagnets and permanent magnet?
Electromagnets are non permanent magnets. They got magnetic field because of applied electric field. They lost their magnetic field which was around that, when the applied electric field is stopped. permanent magnets have magnetic property always with it. Permanent magnetic property loses when we heat the material. It cannot be regained once again. But electromagnets are capable of regaining its magnetic properties.
What is the purpose of the coil in a speaker?
The coil produces a magnetic field. When power is applied to the wire in the coil, the result is a magnetic charge. This magnetic charge is part of how the speaker produces sound.
How does a magnetic substance turn into an electromagnet?
Magnetic materials (usually iron) is used in the core of electromagnets. A coil is wrapped around this core, an electric current applied and it remains magnetized as long as the current is on. Once the current is turned off, it loses most of it's magnetism.

What are hard and soft magnets?
Hard magnets are those which require a high magnetic field so as to be magnetized. Soft magnets are those which acquire high magnetic flux when a little magnetic force is applied onto them.
What are non magnetic substances?
In non-magnetic materials,the magnetic moments of individual atoms are randomly arranged giving net zero magnetic moment such that these materials are not affected when an external magnetiv field is applied
How would you describe magnetic domains?
Each magnetic domain has a magnetic field. When an external magnetic field is applied, the magnetic domains will partially align, so the magnetic fields reinforce one another - instead of canceling one another, which is what happens when they are randomly distributed.
What is the opposite of magnet?
We usually the term nonmagnetic (or possibly amagnetic) to mean not magnetic. That's the opposite of magnetic, and it means the thing described has no magnetic field impressed upon it, nor will it accept one if it is applied to that thing. Nonferrous and nonmagnetic tools, for example, are used on things that are highly sensitive to damage from magnetic fields. These tools not only are not magnetized, they cannot be magnetized. They won't be attracted to a magnet.
How can magnetism be induced in non magnetic iron?
In a magnetic material that is not a magnet, magnetic domains are arranged in random fashion canceling the net magnetic field. If such a material, like an iron rod, is exposed to a strong magnetic field, the domains will arrange themselves in the direction of the applied field and hence object will become magnetized.
What are magnetic types?
ferromagnetism - permanent magnets, with N and S pole, all the atoms are aligned and 'spin' the same way so the magnetic field is strong in one direction paramagnetism - an object becomes temporarily magnetic when a field is applied and the resulting field is parallel to the applied field diamagetism - a temporary magnetism opposite to that of the applied field
Susceptibility of ferromagnetic substances?
Magnetic susceptibility is the quantitative measure of the extent to which an object may be magnetized in relation to a given applied magnetic field. In ferromagnetic susceptibility, the magnetization is more than 1,000 times larger than the external magnetizing field.
What happens to the electrons in materials that are turned into magnets?
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.

Why a magnet placed inside a solenoid does not show magnetism?
The solennoid is an electromagnet and only becomes magnetized when the power is applied.
