Construction: A motor require essentially a rectangular coil called armature a permanent magnet, a device called commutator to reverse the direction of current and a source of electrical energy like a battery. A shaft is connected to the armature to utilize the mechanical energy so produced.
The rectangular coil ABCD and iron core together constitute the armature. The armature is mounted on the shaft. Two metallic rings C1 and C2 insulated from each other are mounted on the shaft act as commutator.
The ends of ABCD coil are soldered to C1 and C2. The wires from battery B are connected to carbon brushes B1 and B2 which are always in contact with half rings C1 and C2.
The battery B, the key K, the brushes, the commutator and coil form an electric motor.
Transverse Waves: The traveling waves in which particles of the elastic medium vibrate about perpendicular to the direction of propagation of waves are known as transverse wave

Explain the Electromagnetic Induction The force exerted on an electric charge moving in a magnetic field leads to the idea of magnets being able to produce electricity as well
A Rayleigh interferometer (as shown in the figure below) can be used to measure the index of refraction of air. Two transparent tubes (T 1 and T 2 ) are placed behind two slits. O
A charge is said to be in equilibrium, if total force performing on it is zero. A operation of charges is said to be in equilibrium if every charge is independently is equilibrium.
