About This Product
With a variable d.c. supply and a Magnetic Flux Density Meter, the field can be measured at various positions inside and outside the coil for a range of currents, so the relationship between flux density, number of turns, current and coil length can be investigated. With a variable a.c. supply and suitable a.c. meters, the two coils act as primary and secondary of a crude transformer in various turns ratios. Its efficiency is very low, and steel retort stand rods can be added as a core to illustrate increasing efficiency. Besides buyers across India, the Solenoid Superior can be exported to institutions in Bahamas, São Tomé and Príncipe, Montenegro, Madagascar and Mozambique.
Frequently Asked Questions
Q1. How many turns can be selected?
The coil is tapped at 5, 10, 20, 30, 50, 70 and 100 turns on either side of the centre, effectively offering coils from 5 to 200 turns.
Q2. Can the solenoid be used as a transformer?
Yes. With a variable a.c. supply and suitable a.c. meters, the two coils serve as primary and secondary windings in various turns ratios, forming a crude transformer with very low efficiency.
