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.

Magnetic Field Demonstrator, Acrylic
An elegant method for displaying the shape of magnetic fields without using iron filings. Ideal for student investigations or for demonstration using an overhead projector. The transparent plate is comprised of a matrix of small circular chambers. Each chamber contains an iron rod and functions independently as a plotting compass.
