Variable Magnetic Field Coil
An enamelled copper wire solenoid is wound on a clear acrylic tube. The extreme ends of the solenoid are movable and the magnetic field can be varied by moving the extreme ends. 4mm sockets are provided to apply the current across the solenoid. Coil Diameter 60 mm, Length 350 mm.

Ring Launcher
The ring launcher consists of a vertically mounted solenoid of thick copper wire with an iron core. The coil is energized with by pressing the push button on the panel. Two aluminum rings are supplied with the apparatus. These rings fit over the solenoid and are supported at some height above the base by adjustable collar. The behaviour of the rings when the coil is energized depends on the type of the ring placed over the coil at the time. The solid aluminum ring is propelled straight up while the slotted ring remains static, thus demonstrating the principle of electromagnetic induction as well as Lenz law.

Ring Launcher
To demonstrate the Lenz’s law and effects of electromagnetically induced currents. A ring launcher consist of the base unit and built-in vertical solenoid of thick copper wire with a removeable iron core. Launch rings are provided with launcher includes: aluminum ring without split, aluminium ring with split and a plastic ring. These rings fit over the solenoid and are supported at some height above the base by an adjustable collar.
Unique characteristics:
- Circuit activation by insertion of solenoid.
- Buzzer for the confirmation of activation.
- IR remote for safe & controlled launch.

Variable Electromagnet
The variable coil electromagnet has 6 different coil options: 100, 200, 300, 400, 500 and 600 coils. A steel hook underneath gives students the opportunity to measure the strength of the magnetic field generated by varying different numbers of coils. A variable D.C. low voltage supply is required.

Demonstration Relay
This Relay Demonstration Unit allows the investigation and study of how a relay functions in a clear and practical manner. A useful property of this Demonstration Relay Unit is that the circuit powering the coil is easily seen to be completely separate from the circuit-switched on by the relay. This is one of the reasons relays are used where a safe low-voltage circuit can be used to control a high-voltage circuit. When a current flows through the coil an electromagnetic field is produced. This field attracts the iron armature whose end makes the contact, completing the circuit and illuminating the Lamp. When the current is switched off, the contact will open again, switching the circuit off.

Iron-Clad Electromagnet
Used to demonstrate that how electric energy is converted into a very strong magnetic field. The precision machined contact surface makes this electromagnet so strong that it generates tremendous lifting power. The electromagnet is consists of core and yoke with vertically fitted four ‘D’ type cell holders around the electromagnet. The core has a cylindrical coil wound with enameled copper wire on annular insulated bobbin. It can also be operated with 6V/2Amp DC power supply.

Force on a Conductor in a Magnetic Field (Laplace Law)
To demonstrate the electromagnetism. A pair of powerful magnets in U shape holder. A pair of brass rail with 4 mm socket is used for demonstration. A brass axle with two plastic discs is free to roll along the rails and complete the circuit between rails. As the axle placed on the rails near the poles of magnets and power supplied to the rails, the axle repelled and rolls away from the center of magnetic field along the rails.
