Magnetic Field Demonstration Instrument Key benefits Clear visualization of three common magnetic field types: linear current, ring current, and solenoid magnetic fields for effective teaching and demonstration. Stronger, more visible magnetic induction lines thanks to multiturn coils instead of singlecore wire, improving demonstration clarity and student comprehension. Transparent construction lets observers see magnetic field patterns directly; designed for demonstration use and classroom visibility. Simple compatibility with direct current power supplies to show that DC through a conductor produces a magnetic field and to illustrate the relationship between current direction and magnetic field direction. What it does Demonstrates the magnetic field produced by a straight current, a circular current, and a solenoid configuration. Uses multiturn coils in place of singlecore wire to increase magnetic induction intensity and enhance visual effect. Shows the directional relationship between current flow and magnetic field lines with realtime formation of induction lines. Important attributes Function: Educational demonstration of DCproduced magnetic fields for linear, ring, and solenoid configurations. Compatibility: Intended for use with direct current power supplies and standard classroom or laboratory demonstration equipment. Material: Instrument housing and viewing surfaces are made of transparent material; avoid surface friction to maintain transparency and visual clarity. Performance: Multiturn coil design increases magnetic induction intensity to produce clearer and more distinct magnetic lines for observation. Usage note: After magnetic induction lines have formed, cut the power supply to avoid excessive temperatures and potential damage to the instrument and to improve conversion rates. Practical applications Physics classroom demonstrations to help students visualize magnetic field geometry and the right hand rule. Laboratory exercises and instructional labs where clear, repeatable visualization of field patterns is required. Science exhibits or demonstration stations for interactive learning that require a durable, visible instrument. Care and handling Keep the transparent surfaces from scratches and avoid wiping with abrasive materials to preserve visibility. Monitor operating time during demonstrations; switch off the power once induction lines are visible to prevent overheating and instrument damage. Use only appropriate DC power supplies and follow standard laboratory equipment procedures for connections and operation. What makes this product stand out Direct comparison of three magnetic field types in one instrument. Multiturn coils deliver stronger magnetic induction and more pronounced field lines than singlecore wire setups. Transparent design provides unobstructed, handson observation ideal for teaching and demonstration contexts.
