[S4 Physics PMCians]
What we did in 2 hours:
On 26th and 27th Sept, the S4 PH has come together to complete the following:
1) Magnetism and Electromagnetism Secret Enclosed
2) The Final Lap
Always remember:
a) The thumb of the Right Hand Grip Rule represents the magnetic pole in a solenoid while the four fingers represent the direction of the current. While the thumb represents the direction of the current in a SINGLE piece of current carrying wire.
b) Fleming’s Left Hand Rule is used to determine the direction of the force exerting on a current-carrying wire placed in an external magnetic field. However, it cannot be used to explain why the wire moves. Do remember to use the ‘stronger B field to weaker B field’ to explain why.
c) ‘Like’ current attract and unlike current repel.
What you take home:
In this coming week (3 and 4th Oct), we will be embarking on brainstorming exam papers.
Do remember to always bring your Secret Enclosed AND the revision books for all lessons.
Do bring along your calculator for the lesson.
