The MFM‑01 apparatus is designed to experimentally verify Biot–Savart’s Law by measuring the magnetic field generated by a current-carrying conductor. The setup enables students to investigate the relationship between magnetic field strength, distance from the conductor, and current magnitude, thus enhancing their understanding of classical electromagnetism.

The experiment typically uses a circular coil, with a Gaussmeter sensor placed along the axis of the coil to measure the magnetic field at various points. A regulated current source powers the coil, and the readings are recorded to compare with theoretical predictions from Biot–Savart’s Law.

This setup is widely used in physics labs to reinforce the concept of magnetic field generation by electric currents and is suitable for both undergraduate and postgraduate levels.
