1. 23. Electromagnetism L2Last week, we went through an overview of the concepts of electromagnetism, especially on how to apply the right-hand grip rule and Fleming's left hand rule. With your two hands at your disposal, you were given an online mcq test to attempt albeit with guidance from your tutor. Eventhough some of you were struggling with your psycho"motor" skills, many of you were able to ace the test and and a few even obtained full marks! Keep it up! We then moved on to DC motors, a machine that we use in daily life which provides motion in everyday devices like fans, refrigerators and vacuum cleaners. We realised that the concepts we learnt in Electromagnetism are being applied in a DC motor, that the magnetic force due to interaction between magnetic fields is what causes the motor to spin.
