How does electromagnetic induction happen?
A changing magnetic field in a region of space produces an electric field perpendicular to it. That's the basic principle of electromagnetic induction.
An electric field is produced when a magnetic field shifts in a space. Because of this, when magnetic flux shifts through a region, electric currents can flow in closed circuits.
Whether or not there is a closed circuit involved, the fundamental idea remains the same.

Electromagnetic induction occurs when a changing magnetic field induces an electromotive force (EMF) or voltage in a conductor. This phenomenon is described by Faraday's law of electromagnetic induction, which states that the induced electromotive force in a closed loop is proportional to the rate of change of the magnetic flux through the loop. When there is relative motion between a magnetic field and a conductor, or when the magnetic field itself changes, it creates a changing magnetic flux, which in turn induces an EMF in any nearby conductors according to Faraday's law. This induced EMF can lead to the flow of electric current in the conductor if there is a closed path, such as a circuit. Electromagnetic induction is the principle behind the operation of electric generators, transformers, and many other devices in electrical engineering.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
