A minute of shaking creates an hour of light in this self electricity generating pen

The concept is meant for underprivileged children who don’t have access to lighting and want to study – The Lampen is literally a pen with a built-in light. It doesn’t work on magic, but has a logical explanation for functioning. Simply shake the pen for a minute and using the principles of electromagnetic induction, this self-electricity-generating pen lights up for 2 hours. Use it as a stand lamp, flashlight or a pen-light, the choice is yours!

Principle of Self Electrcity-generating

It is a process where a conductor placed in a changing magnetic field causes the production of a voltage across the conductor. This process of electromagnetic induction, in turn, causes an electrical current.
