A homopolar motor is one of the simplest motors built due to the fact that it uses direct current to power the motor in one direction. The magnet’s magnetic field pushes up towards the battery and the current that flows from the battery travels perpendicularly from the magnetic field.
What is a homopolar motor and how does it work?
Homopolar motors have two magnetic poles that are provided by the permanent magnet that is used to create the magnetic field. The homopolar motor is named as this due to it being unlike conventional DC motors; the polarity of the magnetic field emitted by the conductor and the permanent magnets do not change!
How does a simple magnetic motor work?
This simple electric motor works by the magnetic force F = IL x B. The current goes around the coil so that it points one direction in one end of the loop and in the other direction at the other end of the loop. The magnetic field at both of these spots points in the same direction.
How does homopolar motor work for kids?
A homopolar motor creates rotational movement because of what is known as the Lorentz force. What’s happening is that electrical current is flowing from the positive terminal of the battery to the negative and into the magnet.
How does an electric motor work simple explanation?
An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor’s magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor’s shaft.
How does a homopolar generator work?
Working principle of a homopolar generator: due to Lorentz force FL negative charges are driven towards center of the rotating disk, so that a voltage shows up between its center and its rim, with the negative pole at the center.
How do you make a simple homopolar motor?

How can you explain the simple electric motor and generator?
A generator converts mechanical energy into electrical energy, while a motor does the opposite – it converts electrical energy into mechanical energy. Both devices work because of electromagnetic induction, which is when a voltage is induced by a changing magnetic field.
How a motor works physics?
An electric motor converts electrical energy into physical movement. Electric motors generate magnetic fields with electric current through a coil. The magnetic field then causes a force with a magnet that causes movement or spinning that runs the motor.
Why does a homopolar motor spin clockwise?
This electromagnetic field creates a force, called the Lorentz Force, that pushes the copper wire, causing the wire to rotate. Because current only flows in one direction (DC power), the force will push in the same direction (clockwise) every time.
Why does my homopolar motor not work?
If the motor doesn’t begin to spin, try flipping the magnet so the other side is touching the battery. If it still doesn’t work you will need to tweak your wire sculpture. Remove the battery from the magnet while you work, so it does not get too hot.
How does Faraday motor work?
The motor features a stiff wire which hangs down into a glass vessel which has a bar magnet secured at the bottom. … This field interacted with the field around the magnet and caused the wire to rotate clockwise. This discovery led Faraday to contemplate the nature of electricity.
What are the basic parts of a simple electric motor?
A simple motor has the following parts:
- A power supply – mostly DC for a simple motor.
- Field Magnet – could be a permanent magnet or an electromagnet.
- An Armature or rotor.
What is the working of electric motor Class 10?
Working Principle of Electric Motor
The electric motor works on the principle that when a coil is placed in the magnetic field and the current passes through it resulting in rotation of the coil.
