The dual magnet circuit is designed with the magnets. The magnetic induced intensity in the duct is raised to 0 78T. The principle experiment is performed by the jetting fluid of the rocket engine.
In this paper, an IBEM (Indirect Boundary Element Method) is presented for calculating permanent magnet field, and the formula of calculating magnetic field intensity is deduced.
