A 62mm long, magnetic needle made from carbon steel with a brass cup-bearing for low-friction pivoting when used with the needle stand, 52-3318.

• Length 62mm
• Ideal for the study of compasses and magnetic fields
• Accurately balanced
• Eisco type PH0816A

A 100mm long, magnetic needle made from carbon steel with a brass cup-bearing for low-friction pivoting when used with the needle stand, 52-3318.

• Length 100mm
• Ideal for the study of compasses and magnetic fields
• Accurately balanced
• Eisco type PH0816C

A non-magnetic metal pillar with a carbon-steel point, mounted on a stable base. The stand is designed to suspend magnetic needles (sold separately) allowing them to rotate freely. The apparatus is ideal for use in the study of magnetic fields and compasses.

• Overall height 110mm
• Eisco type PH0818A

This apparatus is ideal for demonstrating electric fields between various electrodes. Liquid paraffin is placed in the 90mm diameter petri dish and semolina or fine grass seed is sprinkled on the surface. Various electrode configurations can be arranged in the liquid and when a high voltage is applied via the 4mm terminals the field pattern is generated. The see-through base allows the pattern to be projected via an overhead projector system.

• Supplied without paraffin or semolina
• Dimensions (L x W x H): 150 x 150 x 60mm
• Petri dish 90mm diameter

Tough plastic cased compass with lanyard.

• Marked with four compass points
• Full 360° scale around edge

Compass magnet complete with translucent plastic bowl.

• Plastic bowl marked with compass points
• Watch as the compass points to magnetic north

Buy Iron Filings Magnetic Field (Pack of 10) encased in a plastic bubble.

• Ideal for observing the effects of invisible magnetic fields
• Diameter: 85mm
• Supplied in packs of 10

These iron filings are encased in a plastic shaker, ideal for magnetic and flux experiments.

• Contains approximately 225g

Buy Magnetic Field Display Window (Clear) from Shaw Magnets - magnetic field windows that contain magnetic powder in a water based solution for showing magnetic field patterns.

• When a magnet is present the particles of iron inside become slightly magnetised, so they attract each other and cluster into the lines that show the magnetic field patterns
• Size 225 x 130 x 15mm
• Includes 2x plastic cased magnets, 2x ferrite magnets and an information/instruction booklet
• Transparent background for use with an overhead projector

Buy Magnetic Field Display Window (White) from Shaw Magnets - magnetic field windows that contain magnetic powder in a water based solution for showing magnetic field patterns.

• When a magnet is present the particles of iron inside become slightly magnetised, so they attract each other and cluster into the lines that show the magnetic field patterns
• Size 225 x 130 x 15mm
• Includes 2 x plastic cased magnets, 2 x ferrite magnets and an information/instruction booklet
• White background

Buy Magnetic Globe Set from Shaw Magnets – a two-piece set comprising of a rubberised ball representing the earth. This has a strong magnet moulded within to create an invisible exterior magnetic field similar to that of the Earth.

Also supplied is a hand held magnet called a magnetic field finder which is a type of three dimensional compass. When the magnetic field finder is placed near to the globe, it tilts and orientates itself to clearly show the strength direction of the magnetic flux anywhere around the Earth ball. A really magical way to see and understand the Earth's three dimensional magnetic field pattern.

• Supplied complete with globe, magnetic field finder and full teacher and pupil instructions
• Makes learning both fun and interesting
