Curie Law
Curie law of paramagnetism describes the magnetic susceptibility (χ) of a paramagnetic material as a function of temperature (T). It was formulated by Pierre Curie in the 19th century and is expressed mathematically as:
χ = C/T
where,
- M is Magnetization
- χ is Magnetic Susceptibility
- C is Material-specific Curie Constant
- T is Absolute (Kelvin) Temperature
According to the Curie law, the magnetic susceptibility of a paramagnetic material is inversely proportional to its absolute temperature. Curie law holds true for paramagnetic materials in the absence of external magnetic fields. It describes the behavior of paramagnetic materials above their Curie temperature, which is the temperature at which they undergo a phase transition from a paramagnetic to a non-magnetic state.
Paramagnetism
Paramagnetism is a property where certain materials are weakly attracted to magnetic fields, exhibiting temporary alignment of magnetic moments. This article explores paramagnetism, a property where certain materials weakly respond to magnetic fields. It covers the basics, differences with diamagnetism, factors influencing paramagnetism, and everyday applications like MRI.
