Pulsed field ablation (PFA) is a non-thermal (not using extreme heat or cold) method of biological ablation (removal of structure or functionality) utilizing high-amplitude pulsed (microsecond duration) electric fields to create irreversible electroporation in tissues. [1] [2] It is used most widely to treat tumors or cardiac arrhythmias. [3]
Pulsed-power water treatment is the process of using pulsed, electro-magnetic fields into cooling water to control scaling, biological growth, and corrosion.The process does not require the use of chemicals and helps eliminate environmental and health issues associated with the use and life-cycle management of chemicals used to treat water.

Pulsed magnetic therapy, pulse magnetotherapy (PEMF) [ edit on Wikidata ] Pulsed electromagnetic field therapy ( PEMFT , or PEMF therapy ), also known as low field magnetic stimulation ( LFMS ) is the use of electromagnetic fields in an attempt to heal non-union fractures and depression . [ 1 ]
A longitudinal magnetic field is produced inside a hollow metallic conductor, by discharging a bank of capacitors into the solenoid that surrounds the cylinder. To ensure a rapid penetration of the field in the cylinder, there is a slit in the cylinder, which closes rapidly as the cylinder deforms;
Energy is typically stored as electric potential energy within capacitors, or in the case of explosive pulsed power, as chemical energy.The stored energy is released over a very short time scale resulting in a large amount of power being delivered to a load which can be used to study high energy density physics phenomena such as Inertial confinement fusion using a Z-pinch, and plasma physics ...
Development of pulsed electromagnetic field (PEMF) therapy has been problematical because of the lack of scientifically-derived, evidence-based knowledge of the mechanism of action. For example, PEMF therapy used by plastic surgeons the management of postsurgical pain and edema, [ 11 ] has been criticized for not having a body of evidence for ...
