Oersted’s Law Apparatus STEM Lab Manufacturer,Supplier and Exporter in India
Product Code : SCL-M-12513
Quick Answer: The Oersted’s Law Apparatus STEM Lab shows that a current in a wire makes a magnetic field: a wire frame runs above and below a compass, and the needle swings when current flows. It has 4mm red and black binding posts and works on 1.5V to 6V DC.

About This Product
The base is turned until the needle lies along the wire in a north-south line; closing the circuit briefly then swings the needle to nearly square with the wire. Students predict the direction with the right-hand grip rule, reverse the current at the binding posts and see the needle turn the other way, repeating the 1820 observation that linked electricity and magnetism. Schools, colleges and institutes in Guinea-Bissau, Afghanistan, Senegal, Benin, São Tomé and Príncipe and Côte d'Ivoire can order the Oersted’s Law Apparatus STEM Lab from Educational Instrument.
Frequently Asked Questions
Why must the wire be lined up north-south on the Oersted’s Law Apparatus STEM Lab?
With the wire along the compass needle, the field from the current acts across the needle, so the deflection is large and easy to see.
