The MacBook and the 13-inch MacBook Pro use a 60 W MagSafe charger, whereas the 15- and 17-inch MacBook Pro use an 85 W version. The MacBook Air used a lower-powered 45 W version. According to Apple, an adapter with a higher wattage than that originally provided may be used without problems. [12]
The first car to use magneto ignition was the 1901 German Mercedes 35 hp racing car, followed by various cars produced by Benz, Mors, Turcat-Mery, and Nesseldorf. [8] Ignition magnetos were soon used on most cars, for both low voltage systems (which used secondary coils to fire the spark plugs) and high voltage magnetos (which fired the spark ...
Illustration of the right-hand rule for the Lorentz force, cross product of an electric current with a magnetic field. The working principle involves the acceleration of an electrically conductive fluid (which can be a liquid or an ionized gas called a plasma) by the Lorentz force, resulting from the cross product of an electric current (motion of charge carriers accelerated by an electric ...
The charger uses a circle of rare-earth magnets. [1] Apple released two chargers using the MagSafe standard in 2020: the MagSafe Charger, which is a single charging pad for iPhone, and the MagSafe Duo Charger, which is a charging mat with both MagSafe and an Apple Watch charger. [2]
Another device described as 'electronic' is the 'Electronic Engine Ionizer Fuel Saver'. Testing of this device resulted in a loss of power and an engine compartment fire. [2] There are also 'emissions-control defeat devices' that operate by allowing a vehicle's engine to operate outside government-imposed tailpipe emissions parameters. These ...

On the forward end of the car's drive shaft, was an electric motor with an armature fitted into an air space inside the whirling magnet. Electric current, transmitted by the engine's generator and magnet attached to the armature of the electrical motor, providing the energy to turn the drive shaft and propel the engine's rear wheels.
