Build a real wireless power transfer model and see mutual induction at work. Connect a 9V battery and the LED on the receiver coil lights up without any wires between the coils.
What's in the box
Pre-mounted transmitter coil and receiver coil
Transistor and resistor assembly, LED indicator and 9V battery clip
Circuit layout sheet and printed instruction page (with working principle and notes on mutual induction)
What students learn
Mutual induction, electromagnetic fields and wireless power transfer
Primary and secondary coil interaction and transistor switching
Perfect for
Class 12 physics projects, CBSE exhibitions, STEM learning and science fairs. Suitable for ages 14+.
Please note: A 9V battery is not included (any standard 9V battery works). Use only a 9V battery – do not connect to a higher-voltage source.
