Finding the magnetization vector and magnetic field?

In summary, the magnetization vector is a measure of the magnetic moment per unit volume of a material, representing the overall magnetic alignment of the atomic or molecular dipoles within it. It is affected by factors such as composition, crystal structure, temperature, and external magnetic fields. The magnetization vector creates the magnetic field, which is determined by its orientation and magnitude. The vector can be measured using techniques like vibrating sample magnetometry, SQUID magnetometry, and magnetic force microscopy. It can also be changed by applying an external magnetic field or altering the temperature, a process known as magnetization reversal used in applications such as data storage and magnetic sensors.

Hello,
I've been stuck on this question for a few hours and I hope someone can help. Here is the question:
"Consider two materials bismuth and aluminum with χ m = −20 ×10−5 and
χ m = 2 ×10−5, respectively. Find the magnetization vector and the magnetic field
in these materials when they are under an external magnetic field of 1 T in
direction x."

SO far what I have is this: magnetic susceptibility is defined by Xm= M/H = ur-1, and then M= (sigma Um)/ Volume. However, I am not sure where to go from here..

Related to Finding the magnetization vector and magnetic field?

1. How do you define the magnetization vector?

The magnetization vector is a measure of the magnetic moment per unit volume of a material. It represents the overall magnetic alignment of the atomic or molecular dipoles within a material.

2. What factors affect the magnetization vector?

The magnetization vector is affected by the magnetic properties of the material, such as its composition, crystal structure, temperature, and external magnetic fields.

3. How is the magnetic field related to the magnetization vector?

The magnetic field is created by the magnetization vector. The direction and strength of the magnetic field are determined by the orientation and magnitude of the magnetization vector.

4. How is the magnetization vector measured?

The magnetization vector can be measured using various techniques, such as vibrating sample magnetometry, SQUID magnetometry, and magnetic force microscopy. These methods involve applying a known magnetic field and measuring the resulting magnetization of the material.

5. Can the magnetization vector be changed?

Yes, the magnetization vector can be changed by applying an external magnetic field or by altering the temperature of the material. This process is known as magnetization reversal and is used in various applications, such as data storage and magnetic sensors.
