A new method for measuring the magnetic field of the current-carrying conductor is introduced. By using a new type of weak magnetic sensor, the magnetic field value is presented directly, which overcomes the shortcomings of not measuring the magnetic field of the current-carrying direct conductor at present and only using indirect method to measure the magnetic field of the conductor ring. The experimental principle, method and results of magnetic field excitation by the current-carrying circular conductor and current-carrying straight conductor are given, which is in agreement with the theoretical calculation. This method is simple and intuitive. It can also measure the geomagnetic field, permeability and electromagnetic radiation of mobile phones, improve students' interest in experiments and inspire innovative thinking.
