Magnetic Field Along Straight Conductor

Product Code : SCL-M-12426

Magnetic Field Along Straight Conductor by Educational Instrument is a physics laboratory apparatus designed to demonstrate the magnetic field produced around a straight current-carrying conductor. It is widely used in school physics labs, college practical rooms, STEM laboratories, and classroom demonstrations for teaching the relationship between electric current and magnetism.

This apparatus helps students understand that when electric current passes through a straight conductor, a circular magnetic field is produced around it. The direction of the magnetic field can be observed using a compass needle and explained with the right-hand thumb rule. It is suitable for lessons on electromagnetism, magnetic field direction, current-carrying conductors, and basic principles related to Oersted’s experiment.

Product Description

The Magnetic Field Along Straight Conductor apparatus generally consists of a straight conducting wire mounted on a stable insulated base with red and black terminals for electrical connection. When connected to a suitable low-voltage DC power supply, current flows through the conductor and produces a magnetic field around it.

A compass box or magnetic needle can be placed near the conductor to observe the direction of the magnetic field. By reversing the current direction, students can observe the reversal of compass deflection, making the apparatus highly useful for practical demonstration of electromagnetic principles.

Educational Instrument offers this apparatus for structured laboratory teaching, practical experiments, STEM demonstrations, and institutional physics lab setups.
