Ferromagnetism - thought problem

In summary, The conversation discusses the possibility of using a weak magnet and two ferromagnetic materials, one of higher susceptibility than the other, to create a stronger magnetic field. The idea is to use the strong magnetic field from the first material, which is saturated by the magnet, to saturate the second material. This concept may seem crazy, but there is no apparent issue with it. The person asking for an explanation and questioning the feasibility of the idea.

Hi!

This might be a dum idea but here goes.
Say you have 3 items. One weak magnet and two ferromagnetic materials of different susceptability.
The magnet is strong enough to saturate the first material bot not the second. But since the saturated field in the first material is larger than that from the magnet, can this possibly be used to saturate the second material?

If this concept works one could propagate a magnetic field through materials of different susceptabilities to get a much stronger field at the other end. Which sounds a bit crazy.

Can someone explain this?

Why wouldn't it work ?
Why do you think it sounds crazy ?
I don't see any problem.o_O
 

Related to Ferromagnetism - thought problem

1. What is ferromagnetism?

Ferromagnetism is a physical phenomenon where certain materials become permanently magnetized when exposed to an external magnetic field.

2. How does ferromagnetism work?

Ferromagnetism is caused by the alignment of individual magnetic moments, known as spins, in the material. When exposed to a magnetic field, these spins align in the same direction, creating a larger magnetic field and making the material magnetic.

3. What materials exhibit ferromagnetism?

Common examples of materials that exhibit ferromagnetism include iron, cobalt, nickel, and certain alloys such as steel. However, not all forms of these materials are ferromagnetic, as their structure and composition play a crucial role in determining their magnetic properties.

4. Can ferromagnetism be turned on and off?

Yes, the magnetic properties of ferromagnetic materials can be turned on and off by exposing them to an external magnetic field. When the external field is removed, the material will retain its magnetization.

5. What are some practical applications of ferromagnetism?

Ferromagnetic materials have a wide range of practical applications, including in electrical motors, generators, and transformers. They are also used in magnetic storage devices like hard drives and credit cards, as well as in medical imaging technology such as MRI machines.
