Research and Education
The Qosain Scientific Electromagnet is a precision-engineered tool designed to facilitate advanced experimentation and practical learning in physics, engineering and allied disciplines. For example, this magnet can be employed for producing magnetic fields for investigating magnetic braking due to eddy currents, creating vivid demonstrations for the movement of paramagnetic liquid oxygen, verification of Faraday's laws, and magneto-optical experiments such as the Faraday and Kerr effects. Compact, modular, and safe, it is ideally suited for use in classrooms, laboratories, and academic research settings.
The system is optimized for repeatability, easy integration, and compatibility with standard lab equipment.
To characterize the magnet's performance, detailed tests were conducted using a third-party power supply. The accompanying graphs of magnetic field strength vs current—taken at 20 mm and 30 mm pole separations—show how the magnetic field intensity varies with both input current and distance between poles. These results help users design reproducible and accurate, data-driven experiments tailored to their learning or research goals.
A coil heating profile is also provided, measuring temperature over time under different current loads. This data helps in assessing the electromagnet’s thermal behavior and guides users in maintaining safe operating conditions during prolonged use. The client must note that at the moment, the electromagnet is not water-cooled.
A detailed thermal performance profile is provided, presenting the gradual increase in coil temperature during sustained operation. Accompanying this is a graph depicting the corresponding decrease in voltage, attributed to the inherent rise in coil resistance with temperature—offering a precise characterization of the system's electrical behavior under thermal influence.
