Magnetic Field Demonstrator
Consist of a closed transparent box with a transparent tube through the center. The box contains iron filings and silicon oil. When one or more cylindrical magnets are inserted into the central tube, the filings are attracted and line up along the field lines in all dimensions. With Cylindrical Magnet.
SKU: PH41275Magnetic 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.
SKU: PH40100PMagnetic Force Accelerator
A ramp with metal sides is filled with permanent magnets, North Pole up, covered with a large label. Three Aluminium tubes of different diameters can be placed in turn across the ramp, connecting the metal sides. A 12 V DC voltage is applied to the sides of the ramp so that a large current flows (up to 15 A). The Aluminium tube is immediately accelerated rapidly along the ramp and shoots off the end, breaking the circuit. As well as confirming the Right Hand Rule, students can observe the difference in the current drawn by the tube when the ramp is horizontal and when one end is raised using the included wooden prop. Requires a power supply that can deliver 12 V DC / 15 A, not included.
SKU: PH41170MMagnetic Induction Circuit Board
It is an apparatus to demonstrate the fundamentals of magnetic induction. Students can find relationship between magnetic field strength and induced voltage. The unit is complete with a coil fixed in the board, a cylindrical magnet, a pair of connecting leads and a galvanometer. With instruction manual.
SKU: PH41157Magnetic Kit
A kit of magnets and accessories in a storage tray. Contents : 1. One Horseshoe magnet, 100 mm, with keepers.Two ceramic bar magnets, 75 mm long. 2. Three ceramic ring magnets, 38 mm diameter 3. Two plotting compasses clear both sides, 19 mm diameter 4. One lodestone specimen. 5. One pack Iron Filing. 6. One each strip of Iron, Aluminium, Zinc and Copper metal.
SKU: PH41130Magnetic 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.
SKU: PH40098Magnetic Stirrer With Hot Plate
For simultaneous heating and stirring of solutions. A cast stainless steel hot plate is mounted above a variable speed magnetic stirrer. An Energy regulator for the hot plate, on/ off switch and continuous speed control for the stirrer motor mounted on the front panel. Supplied completed with Teflon coated stirrer bar of size 9 x 25 mm and 9 x 35 mm. Maximum Temperature Range 400°C Heat Output 400 W, Capable of stirring up to 2 liters.
