Description
ABSTRACT
Electricity is carried by current, or the flow of electrons. One useful characteristic of current is that it creates its own magnetic field. This is useful in many types of motors and appliances. This experiment was Conducted to show how electricity was produces using magnet. In this work, we are going to use the principle of electromagnetic induction to generate electricity. We’ll be studying how the number of coils of wire and movement of the magnet can affect the current generated during electromagnetic induction.

CHAPTER ONE
- INTRODUCTION
- Electricity is one of the wonders of the modern world. It keeps our meat and produce fresh, preventing the spread of food-borne illness. It lights the way, both for cars and pedestrians outside, and in our buildings. You’re using electricity right now to power your computer or phone. But how do you make electricity?. The answer is through a process called electromagnetic induction. During electromagnetic induction, large coils of wire are rotated through a magnetic field. The magnetic force causes electrons, tiny negatively charged particles, to move in the wire. The movement of electrons creates a current, which is the electricity we know and love. Current has direction, based on which way the electrons move, denoted by a positive or negative number. The main aim of this work is to observe how current can created using a magnetic field.
1.1 BACKGROUND OF THE STUDY
That magnets can create electricity was discovered accidentally by Hans Christian Oersted in 1819 while giving a lecture. Waving a magnet past a circuit, he made an ammeter twitch. By 1831, Englishman Michael Faraday and American Joseph Henry independently had formalized the theory for this “induction” of a current. Specifically, because the wires cut the magnetic field lines while the magnet is moving, a quantifiable electromagnetic force arises in the wire–pushing electrons and thus making a current.
Attach the ends of one of the two wires to the two contacts of an ammeter.
Wave a magnet over the wire. The ammeter should register both positive and negative current as you wave it back and forth.
Make the circuit a little more complex–a little more like an AC generator–by attaching the two wires to the two ammeter contacts, and attaching the available ends of the wires to the opposite ends of a metal coil. Use a coil that is larger than the magnet, so the magnet can fit inside.
Insert the (rodlike) magnet into the coil and take it back out again. As you do this repeatedly, the ammeter needle should bounce back and forth, again registering current in a positive and negative direction.
1.2 AIM OF THE STUDY
Electric generators are devices that use alternating magnetic fields to create a current through a wire circuit. The main aim of this work is to generate electricity using a moving magnet.
1.3 OBJECTIVE OF THE STUDY
At the end of this work, Students will be able to:
- The generation of electricity
- Explain the relationship between the flow of current and magnetism, and show how this is the basis for electric motors and generators.
- Observe how current can created using a magnetic field.
1.4 PURPOSE OF THE STUDY
To generate an electric current using a magnetic field
1.5 SCOPE OF THE STUDY
The properties of magnets are used to make electricity. Moving magnetic fields pull and push electrons. Metals such as copper and aluminum have electrons that are loosely held. Moving a magnet around a coil of wire, or moving a coil of wire around a magnet, pushes the electrons in the wire and creates an electrical current. Electricity generators essentially convert kinetic energy (the energy of motion) into electrical energy.
1.6 SIGNIFICANCE OF THE STUDY
The discovery of electromagnetic induction is very important in our lives because it is the principle by which electric generators can make electricity which has the same principle with this work. Through the use of magnets, a generator can convert mechanical energy to electrical energy (by moving magnet around copper wire) and provide electricity that we need for so many things.
1.7 APPLICATION OF THE STUDY
The principle of generating electricity is applicable to devices like:
- Wind turbine
- Gas turbine
- Ac and dc alternator or generator
- Induction cooking
- Induction motors
- Induction sealing
- Induction welding
- Inductive charging
- Magnetic flow meters
- Wireless energy transfer, etc.
