DEVICE TOPIC THEORETICAL Lenz’s Law Demonstration
... emf and induced current is determined from Lenz’s Law which states that the polarity of the induced emf is such that it tends to produce a current that will create a magnetic flux to oppose the change in the magnetic flux through a loop. For this demonstration to work effectively, a magnet is droppe ...
