PlanningAimTo find the factors that affect the amount of E.M.F. being produced. The amount of E.M.F. produced during the experiment when each type of factors is change.Background knowledgeElectro-motive-force is the energy being supply to a charge. Battery is a type of energy. The energy that it provides is voltage. Battery voltage is sometime called electro-motive-force because it is used to "pump" around the electrons in the wire. The force can be generates by the moving of magnetic field as in the left-hand rules (field, current and force). It is the force that pushes the electrons around the circuit from the positive pole to the negative pole. That is why current directions in circuits are always marked from positive to negative.The voltage of the batteries varies in many volts e.g. 1.5V, 6V etc. A battery with a voltage of on volt is able to deliver one joule of energy for each coulomb of charge that passes through it. In other words, the voltage of a battery is the number of joules per coulomb that the battery can deliver when it is connected in a circuit.The law of left-hand rules or Fleming rules is that:* Thumb is for Motion.* First finger is for Field.* Second finger is for Current.Hypothesis* Does the change of frequency of the current affect the amount of electro-motive-force being produced?* Does the change of current affect the amount of electro-motive-force being produced?* Does the number of coil of green wire affect the amount of electro-motive-force being produced?* Does the number of coil of wire use for magnetizing the irons affect the amount

of electro-motive-force being produced?Apparatus1. AC power supply - provides electricity to the circuit.2. Signal generator - for providing the electricity the circuit and also for changing the frequency of the current.3. Ammeter - for measuring the amount of amp being produced.4. Coil of wire - produce the magnetic field, which magnetize the pieces of iron.5. Two pieces of iron - to be magnetized into a magnet.6. Circuit wire - for connecting up the circuit.7. Oscilloscope - for measuring the amount of electro-motive-force being produced.8. Green wire - attached to oscilloscope carrying the electro-motive-force to it to be measure.PlanningSafety precaution* Electricity ...
