What drives electric clippers besides a rotary and magnetic motor?

Pivot motor
Solar power
Manual power
Hydraulic system

The correct answer is: Pivot motor

Rotary and magnetic motors are commonly used in electric clippers as they are efficient and powerful. Solar power is not a suitable option as it is not commonly used to power electric clippers and may not provide enough energy consistently. Manual power would require the user to continuously crank a handle which would be inconvenient and tiring. A hydraulic system would also be impractical as it would add unnecessary and complex mechanics to the device. Therefore, pivot motor, which uses an off-center bearing to produce a back and forth movement, is the most practical and commonly used option for driving electric clippers.
