The correct answer is 'a) By changing magnetic field'. Electromagnetic induction is a phenomenon in which a change in the magnetic field induces an electromotive force (EMF) in a conductor, causing a current to flow in the conductor. This can be achieved by changing the magnetic field, either by changing the magnetic flux through the coil or by changing the orientation of the coil relative to the magnetic field.
