Magnetic systems could be of two types they are singly exited and multiply exited magnetic systems. In singly exited magnetic systems usually one electrical source is employed.It is generally used to attract or repel hence to make devices like relays,electromagnets etc. Single Excited Electromagnetic System Let us look how an energy build up happens in [...]

The phenomenon by which an emf is induced in a conductor when it is cut by magnetic flux is known as electromagnetic induction. Faraday’s First Law It states that,When ever a conductor cuts a magnetic field or viceversa an emf is induced in it and it setsup in such a direction so as to oppose [...]

The advantage of electrical energy over other energies is that it could be transmitted over a long distance without much loss and with high efficiency.The devices which convert electrical energy into other forms of energy is known as electromechanical devices and the process is known as electromechanical energy conversion.The conversion takes place through either electrical [...]
