Consider a cylindrical copper coil connected serially to a galvanometer . a strong magnet with north or south pole is taken towards it. and coil is moved up and down.
when ever there is a relative motion between coil and the magnet the galvanometer shows deflection . indicating flow of induced current.
the deflection is momentary . it last so long as there is relative motion between coil and magnet.
the direction of induced current changes if magnet or coil is moved towards or away frm it
the deflection is more when the relative motion is faster or less when it is slow.

electromagnetic induction i.e currents can be induced in coils (Select...
Explanation:
Electromagnetic induction is the process of generating an electromotive force (emf) or voltage across a conductor in a changing magnetic field. This phenomenon was discovered by Michael Faraday in the 19th century.
Principle of Electromagnetic Induction:
The principle of electromagnetic induction states that a changing magnetic field induces an electromotive force (emf) in a conductor. This emf can cause a current to flow in the conductor if the circuit is closed.
Conditions for Inducing Current in a Coil:
To induce a current in a coil, the following conditions must be met:
1. Relative Motion: There must be relative motion between the coil and the magnetic field. This means that either the coil moves or the magnet moves.
2. Changing Magnetic Field: The magnetic field must change in strength or direction. This can be achieved by moving the magnet towards or away from the coil, or by changing the current flowing through a nearby coil.
Option C - if relative motion of coil and magnet is present:
The correct answer is option C - if relative motion of coil and magnet is present. This means that the coil and the magnet must move with respect to each other to induce a current in the coil.
When there is relative motion between the coil and the magnet, the magnetic field experienced by the coil changes. This changing magnetic field induces an emf in the coil according to Faraday's law of electromagnetic induction. This emf can cause a current to flow in the coil if the circuit is closed.
It is important to note that the induced current in the coil depends on the rate of change of the magnetic field and the number of turns in the coil. The greater the rate of change of the magnetic field or the more turns in the coil, the greater the induced current.
Conclusion:
In conclusion, currents can be induced in coils through electromagnetic induction. This can occur when there is relative motion between the coil and the magnet, resulting in a changing magnetic field. Option C - if relative motion of coil and magnet is present - is the correct answer as it accurately describes the conditions required for inducing a current in a coil.
