Electricity and Magnetism Inquiry Card - How Do Batteries Work?
How do electricity and magnetism interact? How does alternating current work? How does quantum teleportation work? How is curium made? How do X-rays use electromagnetic waves? What are electromagnetic waves used for in communication? How are mechanical waves produced?

The two are connected to the same sun and planet gear system, which, in turn, is connected to a drive unit and the front wheels. Picture by Warren Gretz courtesy of US Department of Energy/National Renewable Energy Laboratory (DoE/NREL). Image ref 46009. Hybrids come in various flavors. ...
The electricity magnetizes the electromagnet. Increasing current boosts the electromagnet's magnetic force, and decreasing current lowers the magnetism. When the current jumps to unsafe levels, the electromagnet is strong enough to pull down a metal lever connected to the switch linkage. The entire ...

Nearly all of our cells have the ability to generate electricity. And in this article, we'll look at the role of electricity in the human body and find out how we produce it in the first place. The starting point is simple: Right now, any cells in your body that aren't actively sen...
Because copper sulfate is denser than zinc sulfate, the zinc solution floated to the top of the copper solution and surrounded the zinc plate. The wire connected to the zinc plate represented the negative terminal, while the one leading from the copper plate was the positive terminal. Obviously...
The process includes cutting and coiling the wire, attaching it to the battery clip, submerging the electrodes in water attached to a popsicle stick and connecting the assembly to a volt meter to measure the electricity produced. When the battery is connected briefly, it causes electrolysis, split...
The coil is connected to some copper contacts (top left) that feed the power to the phone's battery.Resonant chargersAlthough they work efficiently and they're generally more convenient than wired chargers, charging mats still have their drawbacks: you can only charge so many devices at once...
