Magnetic induction B (also known as magnetic flux density) has the SI unit tesla [T or Wb/m 2]. [1] One tesla is equal to 10 4 gauss. Magnetic field drops off as the inverse cube of the distance ( 1 / distance 3 ) from a dipole source. Energy required to produce laboratory magnetic fields increases with the square of magnetic field. [2]
The tesla (symbol: T) is the unit of magnetic flux density (also called magnetic B-field strength) in the International System of Units (SI). One tesla is equal to one weber per square metre .
The Tesla Roadster is a battery electric sports car, based on the Lotus Elise chassis, produced by Tesla Motors (now Tesla, Inc.) from 2008 to 2012.The Roadster was the first highway legal, serial production, all-electric car to use lithium-ion battery cells, and the first production all-electric car to travel more than 244 miles (393 km) per charge.

The Tesla Model Y is the first electric vehicle to become the world's best-selling car in 2023, outselling the Toyota Corolla. [1]Battery electric vehicles are vehicles exclusively using chemical energy stored in rechargeable battery packs, with no secondary source of propulsion (e.g., hydrogen fuel cell, internal combustion engine, etc.).
Most electric vehicles today use an electric battery, consisting of electrochemical cells with external connections in order to provide power to the vehicle. [ 63 ] Battery technology for EVs has developed from early lead-acid batteries used in the late 19th century to the 2010s, to lithium-ion batteries which are found in most EVs today. [ 60 ]
The cells within an electric vehicle's battery pack each have an anode (the negative electrode) and a cathode (the positive electrode), both of which are separated by a plastic-like material.
Tesla has announced plans to expand Gigafactory Nevada to add a production line for the Tesla Semi and add additional battery manufacturing capacity. The new area will build the company's latest 4680 battery cells. The facility will be capable of building 100 GWh of batteries annually, enough for 1.5 million light duty vehicles. [108]
A typical 12 V, 40 Ah lead-acid car battery. An automotive battery, or car battery, is a rechargeable battery that is used to start a motor vehicle. Its main purpose is to provide an electric current to the electric-powered starting motor, which in turn starts the chemically-powered internal combustion engine that actually propels the vehicle.
