LED Indicator

EM-6714   - 

When plugged into a detector coil, the LED flashes red or green as the detector coil passes through the magnet to indicate which direction the current flows through the detector coil.

Overview

The Field and Detector Coils are ideal for studying electromagnetic induction and all aspects of Faraday's Law:

For a qualitative demonstration:

With the Bi-Color LED Indicator and a variable gap magnet, students can see when a current is induced in the detector coil.  With the LED indicator plugged into a detector coil, the LED flashes either green or red (depending on the direction of the current flow) as it passes through the magnet.

For a quantitative demonstration:

PASCO's coils can be used with a function generator and an oscilloscope or connected to the 850 Interface.  While driving the field coil with a triangle wave students can move the detector coil to find the strength and direction of the magnetic field in various locations. They can also investigate the angle between the field and detector coils or the effect of varying the driving frequency.
