New Type Solenoid Field Measurement Equipment

DESCRIPTION / TECHNICAL SPECIFICATIONS

Introducing a modern and high-precision experimental system designed for a fundamental topic in science and technology programs the measurement of the magnetic field distribution of a solenoid This new-type apparatus was specifically developed to overcome common problems found in older methods such as low sensitivity interference from residual voltage and output instability caused by temperature rise By utilizing an advanced integrated linear Hall unit this instrument provides stable and reliable results

The primary function of this apparatus is to allow students to accurately map the magnetic field along the axis of a solenoid They can investigate the relationship between magnetic induction and position inside the solenoid thereby calculating the length of the uniform magnetic field region and analyzing the field effects at the boundary or ends This experiment provides clear visualization and quantitative data for the often theoretical-only concept of a magnetic field

Versatility is a key advantage of this device Beyond just mapping the solenoidal field students can also perform other important experiments They can measure the sensitivity of the Hall sensor itself and verify that its output voltage is proportional to the magnetic induction it is subjected to Even more interestingly they can learn to apply the compensation principle to perform a challenging measurement like measuring the horizontal component of the Earth's magnetic field a practical application that demonstrates the power of this measurement technique

The entire system is designed for ease of use and durability in a laboratory environment Equipped with protection devices for the power supply and sensor the instrument is safe for student use The firm structure a precision digital constant current source and a high-resolution digital voltmeter ensure that the data obtained is accurate and repeatable All components are integrated within a convenient portable case for storage and use

As a superior teaching tool this instrument offers a complete package with multiple functions an easy-to-understand design good visualizability and stable data It is an excellent choice for university physics experiments and can provide strong technical support for secondary technical schools It transforms the invisible concept of a solenoid's field into a phenomenon that is tangible measurable and deeply analyzable
