match the actuator to its description

A:Gives precise position control and typically has 4 wires

B:Uses a permanent magnet that spins, while the field electromagnets are stationary

C:Gives low-cost, closed-loop position control.

D:Inductive device that gives binary (2 position) control

1:Solenoid

2.Hobby Servo

3.Brushless DC motor

4.stepper Motor

Solution

Solenoid is long straight coil of wire used to generate a nearly uniform magnetic field, Inductive device that gives binary.

Stepper motor gives precise position control it is a digital version of electric motor

Brushless DC motor uses permanent magnet that spins, while the field electromagnets are stationary

Hobby servo is low cost closed loop control
