Demonstration Electromagnet
Model Number: MTME-21
The Demonstration Electromagnet is a compact apparatus designed to investigate how the strength of an electromagnet changes with electrical input. Micro Technologies supplies the electromagnet mounted on a plastic box and designed for operation from approximately 6–9 V DC. By varying the applied voltage within the specified operating range, users can observe corresponding changes in electromagnetic strength. Its integrated construction and accessible electrical terminals make it suitable for repeated magnetic force and electromagnetism experiments.
Product Specification
The Demonstration Electromagnet is a compact experimental apparatus developed for practical investigation of electromagnetism and the relationship between electrical input and magnetic strength. It provides an integrated setup that makes electromagnetic effects easy to observe and compare.
Micro Technologies supplies the electromagnet securely mounted on a plastic box, providing a stable bench-top arrangement and protecting the internal electrical components during normal operation.
The apparatus is designed to operate from approximately 6–9 V DC. A suitable controlled DC source can be connected to the provided terminals to energize the electromagnet.
When electric current passes through the internal coil, a magnetic field is generated and the magnetic core becomes magnetized. This produces an attractive magnetic force that can be investigated using suitable ferromagnetic objects or compatible experimental accessories.
A key application of the apparatus is demonstrating the change in electromagnetic strength with changing voltage. By adjusting the applied voltage within the specified range, the resulting magnetic effect can be compared under different operating conditions.
The apparatus can also be used to demonstrate that an electromagnet is controllable. Unlike a permanent magnet, its magnetic action is produced when the electrical circuit is energized and substantially reduces when the supply is disconnected.
With an appropriate DC supply, the unit can support investigations involving voltage, current, magnetic force, and electromagnetic behaviour. Measurements should remain within the specified operating limits to avoid excessive coil heating.
Its compact plastic enclosure, integrated electromagnet, and straightforward electrical connection make the Demonstration Electromagnet suitable for repeated magnetism and electromagnetism laboratory investigations.

FAQs
What is the Demonstration Electromagnet used for?
It is used to investigate electromagnetism and demonstrate how electromagnetic strength changes as the electrical input is varied.
What is the operating voltage of the apparatus?
The standard apparatus operates from approximately 6–9 V DC.
How is the electromagnet mounted?
The electromagnet is mounted on a plastic box that provides a compact and stable experimental arrangement.
Can the strength of the electromagnet be changed?
Yes. The apparatus is specifically designed to demonstrate changes in electromagnetic strength when the applied voltage is varied within its specified operating range.
What happens when the voltage is increased?
Within the apparatus's safe operating range, changing the voltage changes the coil current and therefore affects the magnetic field produced. The exact relationship depends on the coil and magnetic core characteristics.
Does the electromagnet remain magnetic when switched off?
Its intended magnetic action is produced primarily while current flows through the coil. Some residual magnetism may remain in the core depending on the magnetic material.
Can magnetic attraction be demonstrated?
Yes. Suitable ferromagnetic materials can be used to observe the attractive force generated when the electromagnet is energized.
What type of power supply is required?
A suitable controlled DC power supply capable of providing 6–9 V is required.
Can the effect of different voltages be compared?
Yes. Different voltages within the specified 6–9 V DC range can be applied to compare the resulting magnetic effects.
Is the external power supply included?
A compatible external DC power source should be selected according to the ordered configuration unless specifically stated as included.
What precautions should be taken during operation?
Operate only within the specified electrical range and avoid prolonged energization if the coil or enclosure becomes excessively warm. Disconnect the power before changing circuit connections.
Can Demonstration Electromagnets be supplied in bulk?
Yes. Micro Technologies can supply Demonstration Electromagnets in bulk for laboratories, universities, colleges, research facilities, scientific equipment distributors, and institutional procurement.
