These days, due to the advancement of science and technology, we feel the use of the magnetic field almost everywhere, which makes us important to know and also the ability to control the magnetic field. Arranged together, we will deal with the desired distribution of the magnetic field. We will refer to some common and repetitive methods in identification, and in this dissertation we will use an innovative method to improve its performance. In them, the antenna is used. We put a number of inductors together in an array and by applying the appropriate current, we obtain the resulting fields at a certain distance from the screen. The important point is that our array has the same Hz components. If the currents are appropriate, it can be used in the gates, for example, because any ferrite object that passes by it can be well detected. In the other case, we will use these arrays in such a way that, like a lens, it concentrates power at a point far from the array, which is used in medical work and to find ferrite objects underground. We will base our work on the law of biosecurity and obtain the required relations from it, and according to the obtained relations, we will design and simulate different modes of field distribution and its construction and its results will help us in many applications. .
