Why does an iron core increase magnetism? Apologies if this more advanced than high school.
EDIT: Disregard, found article on magnetic reluctance.

Why does an iron core increase magnetism?
In summary, the conversation discusses the concept of magnetic reluctance and its relationship with magnetic flux. It is discovered that an iron core can increase magnetism due to its ability to conduct magnetic flux better than air. The conversation also mentions a missing picture of an atomic sheep.

Don't hesitate to comeback when that article stimulates a question. Magnetism is one of those very confusing topics.

It would be very nice if you could share the article, maybe we can make sure it's the right article.Atomic_Sheep said:

It looks like @Atomic_Sheep has other problems that he's dealing with. Wait one...

Just wikipedia https://en.wikipedia.org/wiki/Magnetic_reluctance. Basically I realized that magnetic flux depends on the medium that it's present in. Air isn't very good at 'conducting' flux, iron is.
There was another picture of an atomic sheep floating around the internet, but I can't find it anymore.

1. What is the relationship between iron cores and magnetism?
Iron cores increase magnetism because they provide a path for the magnetic field lines to travel through, making the magnetic field stronger.
2. How does an iron core increase the strength of a magnet?
An iron core increases the strength of a magnet by aligning and concentrating the magnetic domains within the iron, which in turn creates a stronger magnetic field.
3. Can any other material besides iron increase magnetism in a magnet?
Yes, other materials such as nickel and cobalt can also increase the strength of a magnet, but iron is the most commonly used material for this purpose due to its low cost and high magnetic permeability.
4. What is the difference between a permanent magnet and an electromagnet in terms of iron cores?
A permanent magnet has a fixed magnetic field that is always present, while an electromagnet's magnetic field is created by an electric current and can be turned on and off. An iron core is used in both types of magnets to increase their strength, but it is necessary for an electromagnet to function.
5. How does the size and shape of an iron core affect magnetism?
The size and shape of an iron core can affect magnetism by determining the density of the magnetic field lines passing through it. A larger or more compact iron core will have a greater effect on the strength of the magnetic field compared to a smaller or more spread out core. The shape of the core can also affect the direction and focus of the magnetic field.
