How to Make Solenoid Engine (Pictures and Video)

by Aromal Karuvath on

let’s make a solenoid engine. You may have seen many videos of making solenoid engine online. There are hundreds of such videos on youtube. But this project is entirely different. We designed it in a way how automobile engines work. You can see many components similar to those in an internal combustion engine. You can see, pistons, connecting rod, crank, crankshaft, cylinder, cylinder head, flywheel etc. An IC engine works by the explosion of fuel inside the cylinder, whereas in solenoid engine the driving force is Electromagnetism.

Make solenoid Engine

A solenoid is a type of electromagnet when the purpose is to generate a controlled magnetic field. If the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.  In engineering, the term may also refer to a variety of transducer devices that convert energy into linear motion. The term is also often used to refer to a solenoid valve, which is an integrated device containing an electromechanical solenoid which actuates either a pneumatic or hydraulic valve, or a solenoid switch, which is a specific type of relay that internally uses an electromechanical solenoid to operate an electrical switch; for example, an automobile starter solenoid, or a linear solenoid, which is an electromechanical solenoid. Solenoid bolts, a type of electronic-mechanical locking mechanism, also exist.

Things needed to Make Solenoid Engine

  1. ACP sheet or fibre sheet – small pieces
  2. Fibre reeper pieces
  3. Fisher plugs
  4. Screws 1.5”-2nos, 3/4” -4nos
  5. Magnet wire or insulated copper wire- 26 gauge- 30mtrs
  6. Syringe- 2nos
  7. copper wire or GI rod- Guage 12- 30 cm
  8. Copper wire- Guage 18- 30cm
  9. Cylindrical Magnets
  10. Wood wheel

Tools needed to Make Solenoid Engine

How to Make Solenoid Engine

Step 1: Making of Solenoid Cylinder 

  • First of all Cut two Similar Pieces of ACP or fibre sheet.
  • And mark Syringe dia on the sheet. Then Remove unwanted Part.
  • Now cut 2” length from a cylinder part of a syringe. Fix the Syringe piece on the sheet.
  • Now is the time to wind the 26 gauge copper wire on the syringe piece.
  • Wind magnet wire tightly. Minimum turns 60, maximum: as much as possible.
  • The more you wind magnet wire, your engine will perform faster and powerful.
  • Make necessary holes. Watch Video.

Step 2: Making of Piston

  • The Piston has three parts. Piston head, connecting rod and crank.
  • We used a Cylindrical magnet as piston head,
  • fibre reeper-screw arrangement as the connecting rod,
  • a small piece of reeper as the crank.
  • Connecting rod plays an important role in transferring Power to Crankshaft easily.
  • I have made this joint Flexible. Note it.
  • Watch Video For more details

Step 3: Making Crank Shaft

  • Buy 12 gauge copper wire or GI rod from hardware shop
  • Bend it as shown in the Figure

Step 4: Make and break arrangement

  • Use 18 gauge copper wire to set the make and break arrangement.
  • Watch video Once again to know, how to set it.
  • Then Assemble each and every component carefully.
  • Connect a flywheel to one end of the Crankshaft.
  • Use an old laptop ac-dc adapter as Power supply.
  • Connect Leads to the Slip contacts as shown in the video.
  • That’s all.

Keep in Mind

  • Take care while using high-performance adhesive, connecting Adapter to the engine, while using Drill, Angle Grinder etc.

Why neodium cylindrical magnet is used at the the top of piston when there is magnetic field being generated

Karthik s s

neodium cylindrical magnet increases the magnetic flux of the inductor which increase the energy of the inductor thus drives the piston very quickly….

Karthik s s

sir i am at the verge of making this project.But I can’t complete this due to the making of can u plese tell me the dimension of the shaft (length and height of the bend) and also plese provide ur email address for further contact.

We have done more than half of the making but unable to make proper connections. Please guide us through connections in detail. Please reply soon


Is copper wire OK instead of magnet wire. If yes can you pls tell me the no. Of turns required and hoe many volts batteries are required.

Thanks for the vedio , I have make solenoid but my solenoid is very heat . and 2nd magnet is very low …! So how can I sole the issus …fist I provide my data….
fiber reel size
# ID 42 mm
# OD 44 mm
# lanth 100 mm
# Copper insulated wire gauge 19
# number of turn 400
# Wight of copper wire 1105 gm
# iron piston size OD 41mm
# iron piston lenth 100mm
# power 12 v 100 amp 2 bettry


I have little bit doubt in the connection of solenoid cylinder wires with the battery,it is not clearly shown in the video.Will you please help,becau be i am stuck on that part


Tell me more about your Project!!
