E-Field Detector Manufacturer,Supplier and Exporter in India
Product Code : ILS-E-11750
Indian Lab Suppliers supplies the E-Field Detector (Product ID: 11750), part of the Electrostatics range under Electricity and Magnetism. It is a hand-held probe that shows whether an object carries positive or negative charge and roughly how much.
Quick Answer
The E-Field Detector lights LEDs red for positive charge and blue for negative charge, with more LEDs lighting as the detected charge increases. Its probe can locate unknown charges, show charging by induction and, with a voltmeter connected to the ports on its back plate, support a demonstration of the inverse-square dependence in Coulomb's law.
Key Features
Red LEDs for positive charge, blue LEDs for negative charge · More LEDs light as charge increases, for qualitative comparison · Probe for locating unknown charges · Ports on the back plate for connecting a voltmeter · Works as a lecture demonstration or student apparatus

Where This Is Used
Physics teachers use it to make invisible charge visible in lessons on charging by friction and induction, and students use it in practicals on Coulomb's law. It pairs well with the Friction Rod Kit (Product ID: 11756) and Electroscope (Product ID: 11761). Browse the full Electrostatics range or the wider Electricity and Magnetism catalogue.
