“Electromagnetism” is a silent educational film from the late 1920s that explains the basic principles of electromagnetism using simple animations, diagrams, and live-action demonstrations.

Electromagnetic induction can create a voltage by movement of a conductor in a magnetic field. This voltage can make current flow. Transformers use electromagnetic induction to change the voltage ...

How can technology help map the soil (better), and what role can soil scans and scanners play in this? What is possible?

The evolution of industrial heating technologies has followed a fascinating path—from primitive open flames to complex magnetic fields. Today, induction heating stands at the forefront, offering ...

A new video analysis bolsters the theory that an Edison tower — deenergized more than 50 years ago — became active in the ...

Chinese researchers have made new progress in defective cartilage repair with the development of an implantable ...

Introduced in 2009, Qi is based on "closely coupled" electromagnetic induction that requires the device to be aligned on top of the coil on the charging pad. Hundreds of devices are Qi certified ...

The global induction cooktops market is poised for significant expansion, with projections estimating the market size to reach USD 49,917.50 million by 2034, up from USD 22,537.20 million in 2024.

Electromagnetic induction can create a voltage by movement of a conductor in a magnetic field. This voltage can make current flow, and the effect is used in electricity generation and microphones.
