Magnetic far infrared refers to a type of therapy that involves the use of far infrared rays in combination with magnets. Far infrared rays are a type of electromagnetic radiation that is beneficial for promoting blood circulation and reducing pain. When combined with magnets, the therapy aims to enhance the overall healing process and provide relief from conditions such as inflammation and muscle soreness.

Far infrared and thermal infrared are both forms of infrared radiation, but they refer to different parts of the infrared spectrum. Far infrared typically refers to the longer wavelength infrared radiation closer to the microwave region, while thermal infrared refers to the mid- to long-wavelength infrared radiation emitted by objects due to their temperature.
Infrared radiation covers a range of wavelengths longer than visible light, typically from around 700 nanometers to 1 millimeter. The distance it can travel depends on the medium it is traveling through, such as air or water, but typically it can travel several meters before being absorbed or scattered.
Infrared light can travel through a vacuum and is limited by the strength of the source and the sensitivity of the detector. In space, infrared light from distant stars and galaxies can travel vast distances, enabling astronomers to view objects billions of light years away. On Earth, atmospheric absorption limits how far infrared light can travel.
Infrared rays have a longer wavelength than visible light, making them invisible to the naked eye. They are typically in the range of 700 nanometers (near-infrared) to 1 millimeter (far-infrared) in wavelength.
Infrared rays have a range of wavelengths from 700 nanometers to 1 millimeter, corresponding to frequencies of 300 GHz to 430 THz. This range is typically divided into near-infrared, mid-infrared, and far-infrared bands, each with different applications in science and technology.
