Saturation of Y-Shaped Iron with Permanent Magnet

In summary, the top ends of a Y-shaped iron will not be saturated when a Permanent Magnet N pole is placed at the bottom leg, even if there are 20 branches where flux can go. This is because each top end will only have half of the saturation flux density. The H-B curve does not take the cross sectional area into account, but to get the saturation in the branches, one should divide the value of B by 2.

Hi

If we have a Y shape iron and we put a Permanent Magnet N pole at the bottom leg of the Y in such that it will saturate it. would the top ends of the Y also be saturated. what if instead of 2 we have 20 branches where flux can go. what is the saturation will be like at one branch?

thx

No the top ends of the "Y" won't saturate as they will each have only 1/2 of the saturation flux density.

BTW. Since you don't specify then I'll assume that all legs of the Y have the same cross sectional area. Note that typically the "Y" would be connected to some form of yoke to form a complete magnetic circuit.

Then, why the H-B curve does not take the cross sectional area in account?

OR should I take the value of B and half it to get the saturation in the the branches?
 

Related to Saturation of Y-Shaped Iron with Permanent Magnet

1. What is the purpose of saturating Y-shaped iron with a permanent magnet?

The purpose of saturating Y-shaped iron with a permanent magnet is to create a strong and stable magnetic field. This is useful in various scientific and industrial applications, such as in motors, generators, and transformers.

2. How does saturation of Y-shaped iron with a permanent magnet work?

Saturation of Y-shaped iron with a permanent magnet works by aligning the magnetic domains within the iron material. When the iron is exposed to a strong magnetic field, the domains align in the same direction, resulting in a stronger and more uniform magnetic field.

3. What is the difference between saturation and remanence?

Saturation is the point at which the magnetic domains within a material are completely aligned, resulting in a maximum magnetic field. Remanence, on the other hand, is the measure of the retained magnetic field after the external magnetic field is removed. In other words, saturation is the maximum magnetic field that can be achieved, while remanence is the amount of that field that remains after the external source is removed.

4. Can Y-shaped iron be saturated with any type of permanent magnet?

Yes, Y-shaped iron can be saturated with various types of permanent magnets, such as neodymium, ferrite, or samarium cobalt magnets. However, the strength and stability of the resulting magnetic field may vary depending on the type of magnet used.

5. Are there any limitations or risks associated with saturating Y-shaped iron with a permanent magnet?

Yes, there are some limitations and risks associated with saturating Y-shaped iron with a permanent magnet. One limitation is that the saturation point can only be reached up to a certain level, depending on the quality and composition of the iron material. Moreover, the process of saturation can also affect the mechanical properties of the iron, making it more brittle. Additionally, there may be safety risks associated with handling strong permanent magnets, such as the risk of pinching or crushing injuries.
