Year 12 Physics students find the HSC Physics Motors and Generators module conceptually challenging. As such, students struggle to provide scientific responses that are logical and sequential as required to obtain full marks in exam questions.
So, we’ve provided some flowcharts from the Matrix Year 12 Physics Theory Book below to help you write better scientific responses. If you missed it, also read: HSC Physics Study Guide Part 1 (Space Module).
The flowchart below outlines the magnetic field phenomena.
The motor effect refers to a physical phenomenon where a current carrying conductor in an external magnetic field experiences a magnetic force due to the interaction between the magnetic fields.
The flowchart below outlines the process of torque production in a simple brushed DC motor.
A galvanometer is an instrument used to measure the size and direction of electric currents using the principle of the motor effect.
The flowchart outlines how a galvanometer operates.
The flowchart outlines how a loudspeaker operates.
The flowchart outlines the process in which EMF is induced in a moving conductor.
Faraday’s Law can be stated as follows:
An EMF is induced whenever a circuit experiences a change of magnetic flux and the EMF induced in a circuit is directly proportional to the rate of change of magnetic flux through the circuit.
The flowchart outlines the process in which EMF is induced in a moving conductor.
The flowchart outlines the process in which a generator converts mechanical energy into electrical energy using the principle of electromagnetic induction.
If you’re struggling with your Physics marks, you’d better get on top of it before entropy really kicks in. But don’t worry, Matrix is here to help!
