N2 - This paper is focused on numerical investigation of arc during the contact opening process of a DC Relay product. A 3-D air arc model based on magneto-hydrodynamic theory was built and calculated, and the nonlinear permanent magnet and contact opening process were taken into consideration. A method coupling different software was used to fulfill the requirements above, in which fluid field and electromagnetic field were calculated separately. Data transmission between different software was achieved by self-programming file. The distribution of temperature, arc voltage and current curves can be obtained from the simulation. Comparative simulation was carried out to see the influence of Lorentz force generated by magnet on the breaking process of DC relay.
