    Why is magnetic flux through closed surface zero while electric flux not? Gauss’ Law for Magnetism The net magnetic flux out of any closed surface is zero. This amounts to a statement about the sources of magnetic field. For a magnetic dipole‚ any closed surface the magnetic flux directed inward toward the south pole will equal the flux outward from the north pole. The net flux will always be zero for dipole sources. If there were a magnetic monopole source‚ this would give a non-zero area integral

    An electric car is powered by an electric motor instead of a gasoline engine. The electric motor gets energy from a controller‚ which regulates the amount of power transmitted throughout the vehicle‚ based on the driver’s use of an accelerator pedal. The electric motors give electric cars instant torque‚ creating a strong and smooth acceleration pattern. Electric cars are about three times more efficient than cars with an internal combustion engine. A pure-battery electric car uses energy stored

    Heat: a form of energy Heat In physics and chemistry‚ heat is energy transferred from one body to another by thermal interactions.[1][2] The transfer of energy can occur in a variety of ways‚ among them conduction‚[3] radiation‚[4] and convection. Heat is not a property of a system or body‚ but instead is always associated with a process of some kind‚ and is synonymous with heat flow and heat transfer. Heat flow from hotter to colder systems occurs spontaneously‚ and is always accompanied by an
