Simple Machines- Electric Motor

When you think of a motor, the first thing that comes in your mind might be a car. But you actually encounter many motors in your home like a washing machine, fridge, a fan, all these are machines that use an electric motor. The electric motor has demonstrated properties of electromagnetism.

Electric Motor

The principle behind the magnetic field and electric current are a bit technical, but making a simple electric motor is easy. This simple machine project requires just a coil of wire, a magnet and a battery for the power source. By the project of a simple electric motor, you will explore how to build and construct an electric motor and the changes happening after the rotation of the motor.

Simple Electric Motor Project

Do you wish to build an electric motor? You will most probably find just about everything you need around your house. Follow the steps listed here to make a simple electric motor project.

Materials Required

  1. Battery
  2. Insulated wire
  3. Electric tape
  4. 2 metal sewing needles that have long and the eyes must be large enough to fit the wire.
  5. Small circular magnet
  6. Modelling clay
  7. Knife
  8. Thin market


  1. Wrap the wire tightly in a circular motion starting in the centre. Wrap the wire around 30 times.
  2. Wrap the loose end of the wire around the coil and the endpoints should be kept away from the loop.
  3. Remove the insulator from both ends of the wire.
  4. Insert both loose ends of the wire coil into the large eye of a needle. Make sure to keep the coil as straight without bending the wire ends.
  5. Place a battery on a flat surface, use modelling clay to fix it thoroughly.
  6. Place the sharp end of the needle to the battery one at the positive end and another at the negative one.
  7. Cover the sharp ends of the needle with modelling clay.
  8. Secure the needles with electrical tape to the ends of the battery.
  9. Now fix a small magnet on the between the battery and the coil.
  10. Spin the coil, the motor will continue to spin and push in the right direction.


Needles and the wire have created a closed loop circuit. This carries current flow from negative thermal passing the circuit to the positive terminal of the battery. This makes a closed loop and creates its own magnetic field in the coil, which helps to spin.

As you know magnets have two poles: south and north. Opposite poles stick and similar repel. As the magnetic field created by the current in the wire on the coil, the magnet that is fixed to the battery repels the magnetic field of the coil and continues to spin and continuously spin until the battery is dead.
