Magnetic shock absorbers are fabricated using a combination of magnetic and mechanical components.

• Magnetic shock absorbers use a piston that moves through a magnetic field to generate damping force.

• The piston is typically made of a magnetic material such as neodymium or samarium cobalt.

• The magnetic field is created by a series of permanent magnets or an electromagnet.

• The mechanical components include a housing, seals, and a fluid that provides damping.

• The housing is typically...read more

A turbocharger is a device that increases the efficiency and power output of an internal combustion engine by forcing extra air into the combustion chamber.

• Turbochargers use exhaust gases to spin a turbine, which in turn drives a compressor to force more air into the engine.

• This extra air allows for more fuel to be burned, resulting in increased power and efficiency.

• Turbochargers are commonly used in high-performance vehicles and diesel engines to improve performance.

• They can...read more
