Magna Probe
A tool for visualizing the three-dimensional nature of magnetic fields. The sensitive probe allows students to observe magnetic effects in space with clarity. Ideal for individual or group experiments, it provides an engaging way to understand complex concepts in physics through hands-on learning.
Features:
- Small Alnico bar magnet with clear N–S marking
- Non-magnetic gimbal mount for free movement in X, Y, Z axes
- Highly sensitive probe for precise demonstrations
- Approximate Dimensions: 120 mm (head width) × 280 mm (length)

Magnetic Pendulum
The Random Oscillating Magnetic Pendulum (ROMP) is a popular desktop toy. It consists of a pendulum, with a small magnet attached to the end, which can swing freely over a metal base. On the base there are nine numbers of strong, disc-shaped magnets, which act on the pendulum with either an attractive or repulsive force. When the pendulum is displaced and released, it tends to swing in an erratic, unpredictable pattern. Due to friction, the pendulum eventually comes to rest over one of the magnets.

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.
