An Electromagnet Science Project Kit Working Model is an educational tool designed to help students and enthusiasts explore the principles of electromagnetism through hands-on experimentation. These kits typically include various components and instructions to build a functional electromagnet and conduct experiments to learn about its operation. Here’s a description of what you might find in such a kit and how it works:

Coil of Wire: A length of insulated copper wire is provided in the kit. This wire will be wrapped around the core to form the coil of the electromagnet.
Power Source: A power source, such as batteries or a power supply, may be included to provide the necessary electrical current for the electromagnet to function.
Switch: A simple on/off switch is often included to control the flow of current through the coil.
75MM Compass: At the center of the dial, there is a magnetic needle that is free to rotate. This needle aligns itself with the Earth’s magnetic field, indicating the magnetic North direction. The needle is usually red or marked in red to distinguish it from other markings on the dial.
