Why electromagnetic brakes are not use in car and motorbikes?

Electromagnetic brakes are not used in cars and motorbikes because they are not as efficient as other types of brakes, such as disc brakes or drum brakes. Electromagnetic brakes use a magnetic field to create a force that opposes the motion of the vehicle, but this force is not as strong as the force that can be created by mechanical brakes. Additionally, electromagnetic brakes are more expensive and complex to design and build than other types of brakes.

Here are some specific reasons why electromagnetic brakes are not used in cars and motorbikes:

* Low efficiency: Electromagnetic brakes are less efficient than other types of brakes because they convert electrical energy into heat, which is then dissipated into the environment. This can lead to a loss of power and a reduction in the vehicle's range.

* High cost: Electromagnetic brakes are more expensive to design and build than other types of brakes because they require specialized components, such as magnets and solenoids.

* Complexity: Electromagnetic brakes are more complex to design and build than other types of brakes because they require a sophisticated control system to regulate the magnetic field.

* Weight: Electromagnetic brakes are heavier than other types of brakes because they require a substantial amount of metal to create the magnetic field. This can add unnecessary weight to the vehicle and reduce its performance.

For these reasons, electromagnetic brakes are not used in cars and motorbikes. Instead, disc brakes or drum brakes are used because they are more efficient, less expensive, simpler to design and build, and lighter.
