OBJECTIVE:
INTRODUCTION:
EXPERIMENT:
YOU NEED TO KNOW: Lenz's Law and the use of the right hand rule. A varying magnetic field induces a current that opposes the magnetic field change. |
EQUIPMENT:
PRECAUTIONS: The long bar magnet is very fragile! DO NOT DROP IT ON THE FLOOR! |
In addition do not move the pair of red and green magnets any where near the permanent magnet used in EC-5a as this may flip the polarity (North-South) of these magnets. |
PROCEDURE I: (15 min)
