Electromagnetic Circuit Board
Model Number: MTME-28
The Electromagnetic Circuit Board is a compact apparatus designed for the visual demonstration of the electromagnetic field produced by a current-carrying coil. Micro Technologies supplies the unit with compasses positioned around a wire coil located at the center of the circuit board. When current flows through the coil, the compass needles respond immediately and change direction when the current direction is reversed. The apparatus operates from a two D-cell battery arrangement and is supplied without batteries, along with an instruction manual.
Product Specification
The Electromagnetic Circuit Board is designed to provide a clear visual demonstration of the magnetic field generated when electric current flows through a wire coil. Its integrated construction combines a central coil and multiple magnetic compasses on a convenient board-mounted platform.
At the center of the apparatus is a wire coil that generates a magnetic field when current passes through it. The surrounding compasses respond to this field, providing an immediate visual indication of its direction.
Micro Technologies arranges the compasses around the central coil so that the magnetic-field effect can be observed at multiple positions. This makes it possible to examine how the field produced by the coil influences magnetic needles in the surrounding region.
A key feature of the apparatus is its ability to demonstrate the relationship between current direction and magnetic-field direction. When the direction of current through the coil is reversed, the direction of the generated magnetic field also reverses.
The compass needles respond to this reversal by changing their orientation. This provides a clear visual demonstration of the connection between electric current and the direction of the magnetic field it produces.
The apparatus uses a two D-cell battery arrangement as its electrical source. The batteries are not included with the standard unit and should be obtained separately.
Its self-contained board layout minimizes the need for complex experimental assembly. The central coil and compass arrangement are already positioned for convenient observation, making setup straightforward.
The Electromagnetic Circuit Board can be used for investigations involving current-produced magnetic fields, magnetic-field direction, current reversal, compass deflection, and basic electromagnetism.
An instruction manual is supplied with the apparatus to support correct setup and experimental use.

FAQs
What is an Electromagnetic Circuit Board used for?
It is used to visually demonstrate the magnetic field generated by electric current flowing through a wire coil.
Where is the wire coil positioned?
The wire coil is positioned at the center of the circuit board.
Why are compasses placed around the coil?
The compasses respond to the magnetic field produced by the current-carrying coil, providing a visible indication of the field direction at different positions.
What happens when current flows through the coil?
Current flowing through the coil produces a magnetic field, causing the surrounding compass needles to deflect according to the resultant field.
What happens when the current direction is reversed?
Reversing the current reverses the direction of the coil's magnetic field, causing the compass needles to change their orientation.
Can the apparatus demonstrate the relationship between electricity and magnetism?
Yes. The apparatus provides a direct visual demonstration that electric current produces a magnetic field.
What type of power source is required?
The apparatus is designed for operation using two D-cell batteries.
Are the batteries supplied with the apparatus?
No. The required D-cell batteries are not included.
Does the apparatus require an external laboratory power supply?
For the standard configuration, the apparatus is designed to operate from the specified two D-cell battery arrangement.
Is an instruction manual supplied?
Yes. An instruction manual is included with the apparatus.
Can the apparatus be used repeatedly?
Yes. Its integrated board-mounted construction is suitable for repeated electromagnetism experiments when used correctly.
