Lenz’s Law Loop Demonstrator
Model Number: MTME-31
The Lenz’s Law Loop Demonstrator is a simple and effective apparatus designed to demonstrate Lenz’s law and electromagnetic induction. The apparatus incorporates closed and open conductive loops that respond differently when a magnet is moved through or near them. The closed loop shows a mechanical response due to induced current, while the open loop shows little or no corresponding induced-current effect because its electrical path is interrupted. A magnet is not included with the standard apparatus.
Product Specification
The Lenz’s Law Loop Demonstrator provides a clear visual method for investigating one of the fundamental principles of electromagnetic induction. Its open and closed loop arrangement allows the effect of induced current to be compared directly using a moving magnet.
Micro Technologies supplies the apparatus with conductive loop arrangements mounted for easy observation. One loop forms a closed electrical path, while the other incorporates an opening that prevents a continuous current from circulating around the loop.
When a suitable magnet is moved through or near the closed loop, the magnetic flux passing through the loop changes. This changing magnetic flux induces an electromotive force and consequently an electric current in the closed conductor.
According to Lenz’s law, the induced current flows in a direction such that the magnetic field it produces opposes the change in magnetic flux responsible for generating it. This interaction produces a visible mechanical response of the loop.
When the same experiment is performed with the open loop, the electrical path is interrupted. A sustained circulating induced current cannot flow around the loop, so the corresponding magnetic interaction and mechanical response are greatly reduced or absent.
The side-by-side comparison between the open and closed loops makes the apparatus particularly effective for demonstrating that electromagnetic induction involves not only a changing magnetic field but also a complete conductive path for significant induced current to circulate.
The apparatus can also be used to investigate the effect of changing the direction and speed of magnet movement. Faster changes in magnetic flux can produce a stronger induced response, while reversing the direction of motion reverses the corresponding induced-current tendency.
A suitable permanent magnet is required to perform the experiment. The magnet is not included with the standard apparatus.

FAQs
What is the Lenz’s Law Loop Demonstrator used for?
It is used to demonstrate Lenz’s law and show how a changing magnetic flux can induce an electric current in a closed conductive loop.
What types of loops are included?
The apparatus incorporates both open and closed conductive loops for comparative experiments.
What happens when a magnet passes through the closed loop?
The changing magnetic flux induces current in the closed loop. The induced current creates its own magnetic field that opposes the change producing it, resulting in a visible mechanical interaction.
What happens with the open loop?
Because the conductive path is interrupted, a continuous induced current cannot circulate around the open loop, so the corresponding magnetic interaction is greatly reduced or absent.
What does Lenz’s law state?
Lenz’s law states that the direction of an induced current is such that its magnetic effect opposes the change in magnetic flux that produced it.
Does the apparatus demonstrate electromagnetic induction?
Yes. Electromagnetic induction is the fundamental phenomenon demonstrated by the apparatus.
Can the speed of the magnet affect the response?
Yes. Moving the magnet faster changes the magnetic flux more rapidly and can produce a stronger induced effect.
What happens if the magnet direction is reversed?
Reversing the direction of motion reverses the change in magnetic flux and therefore reverses the direction of the induced-current tendency.
Is an external power supply required?
No. The experiment uses the changing magnetic field produced by the motion of a permanent magnet.
Is a magnet supplied with the apparatus?
No. According to the standard configuration, the magnet is not included.
Can the apparatus be reused?
Yes. Its simple mechanical and conductive-loop construction is suitable for repeated electromagnetic induction experiments.
Can Lenz’s Law Loop Demonstrators be supplied in bulk?
Yes. Micro Technologies can supply these apparatus in bulk for laboratories, universities, colleges, research facilities, scientific equipment distributors, and institutional procurement.
