When any material is placed in a magnetic field, there is a slight change in the orbits of their electrons which causes a small magnetic repulsion. This effect is called
a. Paramagnetism
b. Ferromagnetism
c. Diamagnetism
d. None of the other answers
e. Curie Effect
The effect described is called diamagnetism. Diamagnetism refers to the property of a material in which, when placed in a magnetic field, it experiences a weak magnetic repulsion. This occurs due to a slight change in the orbital motion of the electrons within the atoms or molecules of the material.
To determine the answer from the given options, we can go through each choice and eliminate those that do not match the description.
a. Paramagnetism: Paramagnetism is a property of materials that cause them to be weakly attracted to a magnetic field, rather than being repelled. Therefore, this does not match the description.
b. Ferromagnetism: Ferromagnetism refers to the property of certain materials that, when placed in a magnetic field, become permanently magnetized. The effect described in the question is different from ferromagnetism, so we can eliminate this option as well.
c. Diamagnetism: As explained earlier, diamagnetism describes the property of materials that experience a weak magnetic repulsion when placed in a magnetic field. This matches the description given in the question, so it is a possible answer.
d. None of the other answers: Since we have not yet ruled out all the options, we cannot conclude that none of the other answers is correct. Therefore, we do not have sufficient information to select this option.
e. Curie Effect: The Curie effect is a phenomenon that occurs in certain magnetic materials, specifically ferromagnetic materials, where their magnetization decreases as the temperature increases. This is not the same as the effect described in the question, so we can eliminate this option.
Based on the analysis, the correct answer is c. Diamagnetism.
