The high permeability of ferromagnetic materials is due to the alignment of magnetic domains within the material, which allows for easy movement of magnetic flux. This alignment creates a strong magnetic response to an applied magnetic field, leading to high magnetic permeability.

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.
Can a magnet attract aluminum?
Not normally. (Note Alco magnets as an exception.)
Why do magnets only attract to certain metals?
Magnets rely on the semi-free transfer of electrons between the magnet itself and the magnetic object allowing the molecules to be aligned to the same orientation as the magnet. Metals are the most common source of such a material but are not the only elements out there that react to a magnetic field.
How would a glass core affect the strength of an electromagnet?
A glass core would decrease the strength of an electromagnet compared to a core made of materials like iron or steel, which are more magnetic. Glass is not a magnetic material, so it would not contribute to the magnetic field as effectively. Using a material with higher magnetic permeability would enhance the strength of the electromagnet.
Will a magnet stick to aluminim?
No, aluminum is not magnetic so a magnet will not stick to it. Magnetism occurs in materials that are ferromagnetic, such as iron, nickel, and cobalt.
If a material has a high conductivity does it have a high permeability and if so what would be an approximate permeability for the high conductive material?

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.
Permeability refers to?
Permeability is a word used to describe a property of a certain material. It describes whether it will allow another substance such as water to pass through it. To use it in example, one could say 'This cloth is all wet, so it must be permeable'

What is the magnetic permeability of nylon?
Well, nylon is a special material that isn't typically known for its magnetic properties. It's like a happy little cloud floating in the sky, bringing softness and comfort. So, while nylon may not have a significant magnetic permeability, it sure does have a way of making us feel cozy and content.
What is the magnetism of Quartz?
Quartz is not naturally magnetic because it is not a ferromagnetic material. It does not have a magnetic moment itself, so it cannot be magnetized.
Can you magnetize a bit of metal that is not a magnetic type of metal?
Generally, no you can't. A ferromagnetic material has what are called magnetic domains within it. These domains are effectively "tiny magnets" and are randomly arranged when they are in non-magnetized ferromagnetic metals. We can align them and make the material magnetic with the right equipment. A bit of metal that is not ferromagnetic has to domains to realign, so it can't be magnetized.

What happen if the iron core is replaced by gold in the case of transformer?
You will have a very expensive but worthless transformer. Gold is not a ferromagnetic material, so it will not contain the magnetic flux needed to link the separate windings.
Will a North Pole repel a drawing pin?
Yes, a North Pole of a magnet will repel a drawing pin if the pin is made of a ferromagnetic material, such as iron, because the magnetic field of the North Pole will induce a south pole in the pin. However, if the drawing pin is not magnetic or made from a non-ferromagnetic material, it will not be affected by the magnet at all. In most cases, drawing pins are not magnetized, so they would not be repelled by the North Pole.
Is water permeable and saturated?
Water itself is not permeable; rather, it is a fluid that can pass through permeable materials. Saturation refers to the condition in which a material, such as soil or rock, is fully filled with water, meaning it cannot hold any more. In this context, a saturated material allows water to flow through it, depending on its permeability. So, while water can saturate materials, it does not have permeability on its own.
Why do iron and steel stick to magnets?
Iron and steel are ferromagnetic materials, meaning they can be magnetized. When a magnet is brought near iron or steel, the magnetic field of the magnet aligns the magnetic domains within the material, causing them to attract and stick to the magnet.
