A novel B-components approach of the direct solution of magnetostatic field problems is presented. Based on the finite element technique,. the flux density vectors B and field intensity vectors H at nodal points are directly computed by this approach, liquidating the low precision shortcoming of the traditional vector potentical approach for magnetostatic field problems. A typical practical éxample shows that the calculated accuracy of the flux density vector B by this direct approach is an order higher than that by the traditional approach and higher than that of the vector potential,giving a good convergence for the solution as well. Some discretization techniques about B-component equations,matching of the boundary conditions and separation of B-components are also discussed in detail.
