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.
