White Screen Wooden Magnetic Needle on Stand (75mm [confirm] Needle)
The White Screen Wooden Magnetic Needle on Stand is a foundational educational physics laboratory instrument used for demonstrating magnetic fields, compass principles, and polarity. Designed for schools and university laboratories, this apparatus features a highly responsive pivoting magnetic needle mounted in front of a high-contrast white wooden screen. Its primary benefit is allowing educators and students to clearly visualize magnetic lines of force and directional alignment during hands-on science experiments.
Product Description
The White Screen Wooden Magnetic Needle on Stand consists of a sharply pointed, magnetized carbon steel needle resting on a low-friction brass pivot. To ensure maximum visibility in a classroom setting, the stand is affixed to a sturdy wooden base that includes a vertically mounted white wooden screen. This background minimizes visual distractions, making the movement and alignment of the needle immediately obvious from a distance.
Built for the rigors of an educational environment, this magnetism apparatus offers exceptional durability and sensitivity. The needle is precisely balanced to freely rotate in the horizontal plane, responding instantly to the Earth's magnetic field or nearby bar magnets. It is an essential component for any comprehensive physics lab equipment collection, providing reliable, repeatable results for introductory and advanced physics curricula.
Key Features
High-Contrast Background: The white wooden screen provides excellent visibility, allowing students to easily observe needle deflection.
Low-Friction Pivot: Features a precision-machined brass and steel pivot that ensures high sensitivity to weak magnetic fields.
Clear Polarity Markings: The North and South poles of the magnetic needle are distinctly colored (typically red and blue) for instant identification.
Durable Wooden Base: Ensures the apparatus remains stable and level on classroom desks and lab benches.
Long-Lasting Magnetization: The needle is crafted from high-grade carbon steel designed to retain its magnetic properties over extended educational use.
Ease of Use: Requires no assembly or calibration, making it immediately ready for classroom demonstrations.

Applications / Uses
Mapping Magnetic Fields: Used alongside bar magnets to plot magnetic lines of force.
Oersted’s Experiment: Demonstrating the magnetic effect of electric currents when placed near conducting wires.
Studying Earth’s Magnetism: Aligning the needle to find the Earth's magnetic North and South.
Polarity Testing: Identifying the poles of unmarked magnets in educational science kits.
How to Use the White Screen Wooden Magnetic Needle on Stand
Positioning: Place the wooden base on a flat, level, and non-magnetic surface.
Mounting: Carefully balance the magnetic needle onto the sharp point of the central pivot.
Settling: Allow the needle a few seconds to stop oscillating and align itself with the ambient magnetic field.
Experimentation: Slowly bring a bar magnet or an electromagnet near the apparatus to observe the deflection against the white screen.
Safety/Handling Note: Always handle the sharp pivot carefully. Keep the apparatus away from extremely strong neodymium magnets when not in use to prevent demagnetization or reversing of the needle's polarity.
Care & Maintenance
Proper Storage: Store the magnetic needle and the stand in a dry environment to prevent rust on the pivot and needle.
Protect the Pivot: When packing the magnetism apparatus away, remove the needle from the pivot to prevent blunting the sharp point.
Cleaning: Dust the white wooden screen with a soft, dry cloth to maintain high contrast for classroom visibility.
