Question

What are the differences between solenoid and EMF?

Answer 1

The main difference between a solenoid and an electromagnet is the way they function or utilized and the way they are constructed or build..

An electromagnet is a copper coiled or wound around a solid piece of metallic core that when energized becomes a magnet..

While a solenoid is very similar in construction except the core is hollow.. A hollow core where a metallic pin or plunger is positioned. The metallic plunger is mechanically coupled or linked to a mechanism that will open or close a valve, a contact point, etc.

Basically a solenoid is an electromagnet driven mechanism that will convert an electrical energy into a mechanical form..

HERE IS YOUR ANSWER

A solenoid is a cylindrical coil ofwire whose diameter is small compared to its length. When an electric current flows through the wire the solenoid generates a magnetic field similar to that of a bar magnet. An electromagnet is a solenoid wound around a central iron core.
