Diamagnetism Paramagnetism Report

In summary, diamagnetism and paramagnetism are two types of magnetic properties exhibited by materials. Diamagnetic materials are not attracted to a magnetic field and have no permanent magnetic dipole moment, while paramagnetic materials are weakly attracted to a magnetic field and have a permanent magnetic dipole moment. Diamagnetic materials generate a magnetic field in the opposite direction of an external field, resulting in a repulsive force, while paramagnetic materials generate a magnetic field in the same direction, resulting in an attractive force. Examples of diamagnetic materials include copper, silver, bismuth, and gold, while examples of paramagnetic materials include iron, nickel, and cobalt. Temperature has little effect on the magnetic properties of diamagnetic materials,

I am doing an extra-credit report on either Diamagnetism or Paramagnetism, just wondering if any of you can give me any resources on either subject.

Seven of those ten are university sites. You should be pretty safe with those.

Thanx, I treid on Yahoo and didnt really get anything.

1. What is the difference between diamagnetism and paramagnetism?

Diamagnetism and paramagnetism are two types of magnetic properties exhibited by materials. Diamagnetism is a weak form of magnetism where materials are not attracted to a magnetic field and have no permanent magnetic dipole moment. On the other hand, paramagnetism is a stronger form of magnetism where materials are weakly attracted to a magnetic field and have a permanent magnetic dipole moment.

2. How do diamagnetic and paramagnetic materials respond to an external magnetic field?

Diamagnetic materials tend to weaken an external magnetic field as they generate a magnetic field in the opposite direction. This results in a repulsive force between the material and the external field. In contrast, paramagnetic materials tend to strengthen an external magnetic field as they generate a magnetic field in the same direction. This results in an attractive force between the material and the external field.

3. What are some examples of diamagnetic and paramagnetic materials?

Examples of diamagnetic materials include copper, silver, bismuth, and gold. These materials have a completely filled outer electron shell, making them resistant to external magnetic fields. Examples of paramagnetic materials include iron, nickel, and cobalt. These materials have unpaired electrons, which can align with an external magnetic field.

4. How does temperature affect the magnetic properties of diamagnetic and paramagnetic materials?

In general, as the temperature increases, the magnetic properties of diamagnetic materials remain unchanged. However, for paramagnetic materials, the strength of the paramagnetic effect decreases with increasing temperature. This is due to thermal energy causing the unpaired electrons to become more randomly oriented, reducing the alignment with the external magnetic field.

5. Can diamagnetic and paramagnetic materials become ferromagnetic?

No, diamagnetic and paramagnetic materials cannot become ferromagnetic. Ferromagnetism is a much stronger form of magnetism that requires a specific crystal structure and a high concentration of unpaired electrons. Diamagnetic and paramagnetic materials lack these characteristics and therefore cannot exhibit ferromagnetism.
