Question
1. Water exhibits a type of magnetism called ___________________ whereby in the presence of a strong magnetic field, the normally not magnetic water reacts to oppose the strong magnetic field.
2. Ferromagnets exhibit _______________ net magnetization and also exhibit memory, which is seen as a ___________ loop in a plot of magnetization and magnetic field strength.
3. When an ionic compound exhibits two sub-atomic lattices with equal magnetic moments, the material is said to be ________________.
4. The changing of refractive index with changing wavelength of light is known as _______________.
Explanation / Answer
1) Water exhibits a type of magnetism called diamagnetism whereby in the presence of a strong magnetic field, the normally not magnetic water reacts to oppose the strong magnetic field.
2. Ferromagnets exhibit retentivity net magnetization and also exhibit memory, which is seen as a Hysteresis loop in a plot of magnetization and magnetic field strength.
3. When an ionic compound exhibits two sub-atomic lattices with equal magnetic moments, the material is said to be paramagnetic substances.
4. The changing of refractive index with changing wavelength of light is known as refraction.
