What is solenoid?
A solenoid is a coil made by an insulated wire, winding it several times instead of making a single loop, to produce a strong magnetic field.

The electric line of force is the path of a free positive charge that moves in an electric field.
Electric potential of a point is the amount of work needed to move/ bring a unit of positive charge from infinity to that specific point inside the field without producing acceleration.
Electromotive force is the difference in potential that arises between the two ends of a conductor, which gives rise to an electric current.
The mechanical process of storing energy as electric charges by placing an insulating medium between two nearby conductors is called a capacitor.
The process of charging a neutral object by just the presence of a charged object is called electrical induction.
The magnitude of the electrostatic force of attraction or repulsion between two point charges is directly proportional to the product of the magnitudes of charges and inversely proportional to the square of the distance between them and this force acts along the line joining the two charges.
The charge is the fundamental and characterological property of elementary particles that constitute matters.
