Solenoid Engine

What is Solenoid?

A solenoid is a coil of wire that acts as a magnet while carrying an electric current. It is a cylindrical coil wound into a tightly packed helix. Solen means “pipe, channel’ and eidos means “form, shape” in Greek. Andre-Marie Ampere, French physicist invented the term solenoid. The core material that is used in the solenoid is ferromagnetic in nature ie; magnetic lines of flux are concentrated which increases the inductance of the coil. The magnetic flux can be seen outside the coil near the end of the core material but most of the flux is present within the core material.

What is a Solenoid Engine?

A solenoid engine is defined as the engine that works by passing electricity through the coils which makes the pistons to move back and forth due to electromagnetism.

How to make Solenoid Engine?

Materials required:

  • ACP sheet
  • Fibre reaper pieces
  • Fisher plugs, screws (1.5” 2 and 3⁄4” 4)
  • Insulated copper wire
  • 26 gauge 30m
  • 2 syringes GI (galvanized iron) rod 12-30cm
  • Copper wire 18-30cm
  • Cylindrical magnets and wood wheel

Tools required:

  • Angle grinder
  • Drilling machine
  • Drill bit (4mm and 6mm)
  • Cigar lighter
  • Screwdriver and player

Procedure:

  • Cut two similar pieces of ACP sheet and mark the syringe dia on the sheet and remove the unwanted piece.
  • Cut 2” from the cylinder part of the syringe and fix it on the sheet.
  • Take a 26 gauge copper wire and wind it on to the syringe piece.
  • The minimum number turns are 60 and the maximum is as much as possible in order to fix the magnet wire tightly.
  • Before getting the piston ready, it is important to understand that the piston has three parts and they are piston head, connecting rod and the crank.
  • To make piston head, the cylindrical magnet is used, fiber reeper-screw is used as a connecting rod and a piece of reeper is used as the crank.
  • The supply of power to crankshaft happens with the help of connecting rods.
  • Now bend the GI rod in such a way that it forms a wave structure.
  • Use 18 gauge copper wire to make and break the arrangement and assemble all the parts carefully.
  • Connect flywheel to one of the ends of the crankshaft and for power supply, use an old laptop AC-DC adapter.

Now the solenoid engine is ready.

Advantages of Solenoid Engine

  • Solenoid engine causes zero atmospheric pollution.
  • These engines can be used as an alternative to fossil fuels.
  • The engine has more efficiency with lesser torque.
  • The reaction time required for a solenoid engine is very quick.
