Electromagnet vs Solenoid

When searching for electromagnetic actuators, many engineers encounter two similar terms:

Electromagnet

and

Solenoid

Are they the same?

The short answer is:

Not exactly.

Although the terminology varies across different countries and industries, there are important differences in their functions.

Why Are They Often Confused?

Historically, the word solenoid describes a coil of wire.

Since an electromagnet also contains a coil, many people use both names interchangeably.

However, manufacturers often distinguish them by their mechanical function.

Solenoid

A solenoid is designed to create linear movement.

When energized:

• Magnetic field is generated
• Plunger moves
• Mechanical action occurs

Typical applications include:

• Smart Locks
• Vending Machines
• Medical Equipment
• Pinball Machines
• Automotive Actuators

Electromagnet

An electromagnet does not move.

Instead, it generates a strong magnetic field that attracts ferromagnetic materials.

Typical applications include:

• Magnetic Holding
• Door Holding
• Metal Lifting
• Robotic Grippers
• Industrial Automation
• Machine Positioning

Which One Should You Choose?

Choose a Solenoid if you need:

✔ Push

✔ Pull

✔ Linear motion

Choose an Electromagnet if you need:

✔ Holding

✔ Lifting

✔ Clamping

✔ Magnetic attraction

Can Electromagnets Be Customized?
