$262.00(Ex GST)
- Single-turn heavy wire loop rotated by hand around strong rod magnet for core induction demonstrations.
- Loop cuts magnetic field, generates very small induced voltage detectable with a very sensitive meter.
- Demonstrates conductor cutting magnetic lines of force, fundamental electromagnetic induction theory.
- Includes a built-in “mystery” teaching prompt for student discussion during experiments and lessons.
- Optional IEC DC amplifier LB0071-001 boosts small current for reading on student mA bench meters.
- Description
Description
The IEC electromagnetic induction apparatus demonstrates induction at a fundamental level using a single turn of heavy wire rotated by hand around a strong rod-shaped magnet. As the loop cuts the magnetic field, a very small induced voltage is generated that can be detected using a very sensitive meter, making it suitable for clear demonstrations of a conductor cutting magnetic lines of force.
A “mystery” element is included as part of the teaching approach, providing a discussion prompt for students and teachers during the experiment. For easier classroom measurement of the very small output, IEC also manufactures a sensitive low-impedance DC amplifier (LB0071-001) that can amplify the small current so it can be read on a student mA bench meter.
FAQs
Q: What is the main induction method used?
A: A single-turn wire loop is rotated by hand around a rod magnet to cut the magnetic field.
Q: What is generated during rotation?
A: A very small induced voltage that can be detected with a very sensitive meter.
Q: What concept does the apparatus demonstrate?
A: The basic theory of a conductor cutting magnetic lines of force to produce an induced voltage.
Q: What is the “mystery” mentioned?
A: A teaching element included for student and teacher discussion during the experiment.
Q: Is an amplifier available for easier measurement?
A: IEC offers a sensitive low-impedance DC amplifier, LB0071-001, to raise the small current so it can be seen on a student mA bench meter.
