Magnetic Field Along Circular Loop

Product Code : SCL-M-12425

Magnetic Field Along Circular Loop by Educational Instrument is a physics laboratory apparatus designed to study the magnetic field produced by electric current flowing through a circular conducting coil. It is commonly used in school physics labs, college practical rooms, STEM laboratories, and electromagnetic demonstration setups to help students understand the relationship between current, coil geometry, and magnetic field strength.

This apparatus is useful for demonstrating how the magnetic field varies along the axis of a circular loop. It supports practical learning in electromagnetism, current-carrying conductors, magnetic field mapping, and verification of theoretical concepts related to Biot-Savart Law. The setup is suitable for students, teachers, lab instructors, and institutions conducting structured physics practicals.

Product Description

The Magnetic Field Along Circular Loop apparatus generally consists of a circular coil mounted vertically on a stable base, with terminals for connection to a DC power supply. A compass box, magnetic needle, or suitable measuring arrangement can be used to observe the magnetic field direction and variation along the axis of the coil. The coil is positioned in such a way that students can take readings at different points and compare practical observations with theoretical expectations.

Educational Instrument provides this apparatus for academic use where repeatable classroom demonstrations and practical experiments are required. It is suitable for studying the field at the centre of the circular loop, the field along the axial line, and the effect of current variation on magnetic field intensity.

How to Use Magnetic Field Along Circular Loop

Place the apparatus on a stable laboratory table away from strong magnetic materials.

Connect the circular coil terminals to a suitable low-voltage DC power supply through a key and rheostat if required.

Place a compass box or magnetic needle arrangement along the axis of the circular loop.

Switch on the current and allow the needle to settle.

Observe the deflection or field direction at the centre and at different axial positions.

Change the current gradually and note the corresponding change in magnetic field effect.

Record readings in the observation table and compare them with theoretical values or expected field variation.

Switch off the supply after the experiment and disconnect the apparatus safely.
