2. Inductive charging - Wikipedia

   en.wikipedia.org/wiki/Inductive_charging

   Inductive charging is also used in vehicles, power tools, electric toothbrushes, and medical devices. The portable equipment can be placed near a charging station or inductive pad without needing to be precisely aligned or make electrical contact with a dock or plug. Inductive charging is named so because it transfers energy through inductive ...

3. Electrostatic induction - Wikipedia

   en.wikipedia.org/wiki/Electrostatic_induction

   Induction causes a separation of the charges inside the electroscope's metal rod, so that the top terminal gains a net charge of opposite polarity to that of the object, while the gold leaves gain a charge of the same polarity. Since both leaves have the same charge, they repel each other and spread apart.

   Gilbert cloud chamber, assembled An alternative view of kit contents. The lab contained a cloud chamber allowing the viewer to watch alpha particles traveling at 12,000 miles per second (19,000,000 m/s), a spinthariscope showing the results of radioactive disintegration on a fluorescent screen, and an electroscope measuring the radioactivity of different substances in the set.

6. Faraday's ice pail experiment - Wikipedia

   en.wikipedia.org/wiki/Faraday's_ice_pail_experiment

   In his experiment, Faraday closed the opening by attaching the metal lid of the pail to the thread suspending the ball, so when the ball was lowered to the center of the container the lid covered the opening. [1] [3] However this is not necessary. The experiment works very well even for containers with large uncovered openings, like Faraday's pail.

8. Wireless power transfer - Wikipedia

   en.wikipedia.org/wiki/Wireless_power_transfer

   Inductive coupling is the oldest and most widely used wireless power technology, and virtually the only one so far which is used in commercial products. It is used in inductive charging stands for cordless appliances used in wet environments such as electric toothbrushes [57] and shavers, to reduce the risk of electric shock. [78]

9. Battery charger - Wikipedia

   en.wikipedia.org/wiki/Battery_charger

   A charging station sends electromagnetic energy through inductive coupling to an electrical device, which stores the energy in the batteries. This is achieved without the need for metal contacts between the charger and the battery. Inductive battery chargers are commonly used in electric toothbrushes and other devices used in bathrooms. Because ...
