Air Core Solenoid helps investigate the magnetic field of a long coil. It can also used with the Current Balance as an accessory to measure the force on a conductor in a magnetic field. The solenoid has coils wound on a plastic tube with approximately 575 turns of copper wire. It can carry a current of 5 A continuously, or 10 A intermittently.

Moving Coil DC Ammeter (EDM-80). Scale Length approx. 60 mm with anti-parallax mirror scale, dial size 72 x 72 mm with color coded terminals. Overall size 90 x 110 x 125 mm approx. Accuracy : ±2% FSD.

This Instrument is design to demonstrate the method to transmit signals via. Electromagnetic transmission and to study the Amplitude shift keying Modulation and Demodulation. Whole instrument is placed in plastic moulded box and 2 mm banana plug leads are provided for modulation and demodulation connections.

Technical Specification:-
1. Fixed Output DC Regulated Power Supply of ±12 V, +5 V.
2. 100KHz with 5 Vpp amplitude (Approx.) for carrier frequency.
3. In built square wave data generator.
4. Circuit diagrams for Modulator and Demodulator are printed on the milky white top panel.

A printed circuit board coil with 5 and 10 turns. It can be placed between the poles of a permanent magnet on the top pan of a digital balance so that when a current is passed through it, a force is exerted on the magnet due to the magnetic effect of the current. Quantitative measurements can be taken to investigate the formula F = BIL.

General purpose balance for student use. Cast alloy beam fitted with balancing nuts, agate bearings and knife edges. The hangers have double hooks for specific gravity experiments. Detachable nickel plated brass pans, enamelled central pillar, and plumb line, mounted in polished wooden case with levelling screws Capacity 250 gm, sensitivity 2 mg.
