Ampere’s Rule Demonstration Apparatus
Model Number: MTME-40
The Ampere’s Rule Demonstration Apparatus is designed to investigate the magnetic field produced around a current-carrying wire. Micro Technologies supplies the apparatus with a clear acrylic frame, brass conductor, binding posts, one 45 mm diameter compass, and sixteen 16 mm diameter compasses. The arrangement provides a clear visual representation of magnetic-field direction around a conductor and supports practical demonstrations of Ampere’s rule.
Product Specification
The Ampere’s Rule Demonstration Apparatus provides a simple and visual method for investigating the magnetic field generated around a straight current-carrying conductor. It allows the relationship between the direction of electric current and the resulting magnetic-field direction to be observed using magnetic compasses.
The apparatus incorporates a brass conductor mounted within a clear acrylic frame. When electric current passes through the conductor, a circular magnetic field develops around the wire.
Micro Technologies provides multiple magnetic compasses positioned around the conductor. The compass needles respond to the magnetic field produced by the current, providing a visible indication of the field direction at different positions.
The apparatus includes one larger compass approximately 45 mm in diameter together with sixteen smaller compasses approximately 16 mm in diameter. This combination enables the magnetic-field pattern around the conductor to be investigated over multiple points.
The clear acrylic frame provides mechanical support while keeping the conductor and compass arrangement clearly visible during the experiment.
Electrical binding posts are incorporated for convenient connection of the brass conductor to a suitable controlled electrical supply.
When the current direction is reversed, the direction of the magnetic field around the conductor also reverses. This change can be observed through the corresponding change in orientation of the compass needles.
The apparatus therefore provides a practical demonstration of Ampere’s rule and the right-hand rule, helping establish the relationship between current direction and magnetic-field orientation around a straight conductor.
Its transparent construction, multiple compass arrangement, and accessible electrical connections make the apparatus suitable for repeated magnetism and electromagnetism investigations.

FAQs
What is Ampere’s Rule Demonstration Apparatus used for?
It is used to investigate and visualize the magnetic field produced around a current-carrying wire.
What material is the conductor made from?
The apparatus uses a brass conductor.
What material is used for the frame?
The supporting frame is manufactured from clear acrylic.
How many compasses are supplied?
The apparatus includes 17 compasses in total—one larger compass and sixteen smaller compasses.
What is the diameter of the large compass?
The larger compass has an approximate diameter of 45 mm.
What is the diameter of the smaller compasses?
Each of the sixteen smaller compasses has an approximate diameter of 16 mm.
Why are multiple compasses used?
Multiple compasses allow the direction of the magnetic field to be observed at several positions around the current-carrying conductor.
What happens when current passes through the brass conductor?
A magnetic field develops around the conductor, causing the nearby compass needles to orient according to the resultant magnetic field.
What happens if the current direction is reversed?
Reversing the current reverses the direction of the magnetic field around the conductor, which can be observed through changes in compass orientation.
Does the apparatus demonstrate the right-hand rule?
Yes. It can be used to demonstrate the relationship between current direction and magnetic-field direction described by the right-hand rule.
Are electrical connections provided?
Yes. Binding posts are provided for connection to a suitable electrical supply.
Can Ampere’s Rule Demonstration Apparatus be supplied in bulk?
Yes. Micro Technologies can supply this apparatus in bulk for laboratories, universities, colleges, research facilities, scientific equipment distributors, and institutional procurement.
