IGNITOR, SYSTEM AND METHOD OF ELECTRICAL IGNITION OF EXOTHERMIC MIXTURE
The invention relates to an ignitor (1) and a system comprising an ignitor (1), as well as a method of electrical ignition of an exothermic mixture, the ignitor (1) comprising: - a housing (2); - a compartment (3) provided within the housing (2); - a first exothermic mixture (15) of at least a metal and an oxide provided in the compartment (3); - a first electrode (4') connectable to a first terminal of a power supply (17); - a second electrode (4'') connectable to a second terminal of the power supply (17); where at least parts of the first and second electrodes (4', 4'') are in contact with the first exothermic mixture (15); where the first electrode (4') and the second electrode (4'') are provided at a distance (d) from each other, wherein, upon appliance of a voltage above a predetermined threshold value between the first and second electrodes (4', 4'') an electromagnetic field (EMF) is created in the first exothermic mixture (15) between the first and second electrodes (4', 4'').
