What do you understand by magnetic susceptibility?
Magnetic susceptibility is a measure of how well a material can be magnetized in the presence of an external magnetic field. It quantifies the extent to which a material becomes magnetized in response to an applied magnetic field. Materials with high magnetic susceptibility are easily magnetized, while those with low magnetic susceptibility are resistant to magnetization.
Why a piece of iron doesn't behave as a magnet?
A piece of iron doesn't behave as a magnet on its own because the magnetic domains within the iron are not aligned to create a magnetic field. In order for the iron to become magnetized and exhibit magnetic properties, an external magnetic field must be applied to align the domains.
How can a piece of iron be induced into becoming magnetized?
A piece of iron can be induced to become magnetized by placing it in a magnetic field. The magnetic field aligns the magnetic domains within the iron, creating a net magnetic field in the same direction as the applied field. Once the external magnetic field is removed, the iron will retain some level of magnetization.
What is the physical meaning of the slope of the magnetic force vs magnetic field graph?
The slope of the magnetic force vs. magnetic field graph represents the magnetic permeability of the material. A steeper slope indicates a higher magnetic permeability, meaning the material is more easily magnetized by an applied magnetic field. Conversely, a shallower slope indicates lower magnetic permeability.
What happens to a metal object when it is magnitized?
When a metal object is magnetized, its magnetic domains align in the same direction, which creates a magnetic field around the object. This allows the object to attract or repel other magnetic materials. Magnetization can be temporary or permanent, depending on the material and the strength of the magnetic field applied.
What are the domains in a magnetized substance?
In a magnetized substance, domains are small regions where magnetic moments align in the same direction. These domains help create the overall magnetic properties of the material by allowing it to be magnetized and retain its magnetism. When external magnetic fields are applied, domains can collectively align to strengthen the material's magnetic field.

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 role is played by molecular magnets to magnetize and demagnetize bodies?
The relative coercitivity of a material helps to magnetize and demagnetised a substance. If the coercitivity id low then the material can be easily demagnetized and vice versa. A substance can be magnetized by creating magnetic filed of opposite charges and demagnetized by creating same filed of charges.
How can a piece of iron be induced into becoming magnetized?
A piece of iron can be induced to become magnetized by placing it in a magnetic field. The magnetic field aligns the magnetic domains within the iron, creating a net magnetic field in the same direction as the applied field. Once the external magnetic field is removed, the iron will retain some level of magnetization.
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.
What is the physical meaning of the slope of the magnetic force vs magnetic field graph?
The slope of the magnetic force vs. magnetic field graph represents the magnetic permeability of the material. A steeper slope indicates a higher magnetic permeability, meaning the material is more easily magnetized by an applied magnetic field. Conversely, a shallower slope indicates lower magnetic permeability.
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
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.
