When current is applied, a solenoid moves in which type of motion?

• A. Rotary
• B. Linear
• C. Elliptical
• D. Oscillatory

Answer: (B)

When current is applied to a solenoid, it generates a magnetic field that interacts with the coil and any ferromagnetic core present within it. This interaction causes the solenoid to move in a straight line, which is referred to as linear motion. When the current flows through the solenoid, it creates a magnetic force that pulls or pushes the attached movable element (often referred to as an armature) directly along the axis of the solenoid. This linear motion is a fundamental characteristic of solenoids, which are used in various applications such as electromechanical actuators, relays, and various types of switches, where a direct, straight movement is required to perform mechanical work. This principle of linear motion in solenoids is crucial in many systems where precise and rapid actuation is needed.
