Consider a circular loop placed in a time-varying magnetic field. If the magnetic field strength increases uniformly, explain how Lenz’s Law applies and what you would observe in the induced current.
💡 Hint: Apply the concepts discussed about opposing changes and remember the role of induced currents.
If a coil with many turns is in a varying magnetic field and experiences a rapid increase in flux, calculate the expected emf induced, given the rate of change of flux is known.
💡 Hint: Remember the relation between rate of change of flux and induced emf.
