Hall effect and Hall effect method to measure magnetic field in solenoid coil: 1. Understand the principle of Hall element to measure magnetic field. 2. Understand the important physical laws of Hall effect. 3. Understand the characteristics and applications of integrated Hall sensors. 4. Learn to measure the relationship between magnetic field strength and position in an energized solenoid coil. Since the working current of the SS495A integrated Hall sensor is fixed (i.e., standard working current), the sensor must be in this standard state when used. During the experiment, as long as the power supply voltage connected to \"V+, V-\" is adjusted under the condition of zero magnetic induction intensity, so that the output voltage is 2.500 volts, the sensor can be in the standard working state. When there is a magnetic field in the electric solenoid coil, it can be obtained from formula (1):
