Magnetic Field Demonstrator – Long Solenoid
Model Number: MTME-10
The Magnetic Field Demonstrator – Long Solenoid is designed for investigating the magnetic field produced by a current-carrying solenoid coil. Micro Technologies supplies the apparatus with a coil measuring approximately 51 × 92 mm (diameter × length) and wound using approximately 1.5 mm diameter wire. When connected to a suitable controlled electrical source, the solenoid produces a characteristic magnetic field that can be investigated using compatible magnetic-field indicators. The apparatus is useful for observing field direction, field distribution, polarity, and the magnetic behaviour of a solenoid.
Product Specification
The Magnetic Field Demonstrator – Long Solenoid is a practical electromagnetism apparatus developed for investigating the magnetic field associated with a current-carrying solenoid. Its long-coil arrangement provides a convenient configuration for observing the characteristic field produced inside and around a solenoid.
The apparatus incorporates a coil with approximate dimensions of 51 mm diameter × 92 mm length. The winding is formed using wire of approximately 1.5 mm diameter, providing a robust coil configuration for repeated experimental use.
When a suitable electric current passes through the winding, each turn of the coil contributes to the resulting magnetic field. The combined effect produces the characteristic magnetic-field distribution associated with a solenoid.
Micro Technologies supplies the apparatus for investigations of the magnetic field associated with a solenoid coil. Suitable plotting compasses or other compatible magnetic-field indicators can be positioned around the apparatus to observe changes in field direction at different locations.
The solenoid arrangement can also be used to investigate magnetic polarity. When energized, the two ends of the solenoid behave similarly to the north and south poles of a bar magnet. This provides a useful comparison between the magnetic field of a current-carrying coil and that of a permanent magnet.
Reversing the direction of current through the coil reverses the polarity of the solenoid and consequently changes the direction of the magnetic field. This allows the relationship between current direction and magnetic-field direction to be investigated directly.
The apparatus can be combined with a suitable controlled power supply and compatible magnetic-field indicators to perform qualitative investigations of field distribution, polarity, current direction, and electromagnetic behaviour.
Its compact construction, clearly defined coil geometry, and straightforward electrical arrangement make the Long Solenoid Magnetic Field Demonstrator a useful component for repeated magnetism and electromagnetism experiments.

FAQs
What is the Long Solenoid Magnetic Field Demonstrator used for?
It is used to investigate the magnetic field produced by a current-carrying solenoid and to observe field direction, distribution, and polarity.
What is the size of the solenoid coil?
The coil measures approximately 51 mm in diameter and 92 mm in length.
What is the diameter of the winding wire?
The wire diameter is approximately 1.5 mm.
What happens when current flows through the solenoid?
Current flowing through the coil produces a magnetic field. The combined magnetic effects of the turns create a characteristic solenoid field.
Does a solenoid have north and south poles?
Yes. When energized, the two ends of the solenoid exhibit magnetic polarity comparable to the north and south poles of a bar magnet.
Can the direction of the magnetic field be investigated?
Yes. Suitable magnetic-field indicators or plotting compasses can be positioned around the solenoid to observe field direction.
What happens when the current direction is reversed?
Reversing the current reverses the direction of the magnetic field and interchanges the effective magnetic polarity of the solenoid.
Can its magnetic field be compared with a bar magnet?
Yes. The field produced by a solenoid has similarities to the field pattern of a bar magnet, making comparative investigations possible.
Does the apparatus require a power supply?
Yes. A suitable controlled external electrical source is required to energize the solenoid.
Are plotting compasses included?
Plotting compasses or other field indicators should be selected separately unless specifically included in the ordered configuration.
How should the apparatus be operated safely?
Use a suitable controlled supply and avoid excessive current or prolonged energization that could cause the winding to overheat. Disconnect the supply before changing electrical connections.
Can Long Solenoid Magnetic Field Demonstrators be supplied in bulk?
Yes. Micro Technologies can supply these apparatus in bulk for physics laboratories, universities, colleges, research facilities, scientific equipment distributors, and institutional procurement.
