magnetism and electromagnetism test

magnetism and electromagnetism test

In electricity, electrons flow in a circuit (also creating a magnetic field). 1. When a conductor carries an electric current, a magnetic field is produced all along its length. Series - Parallel Circuits Quiz Questions, Series Circuits Calculations Quiz Questions, As the path of an electric current is known as electric current, similarly the path of magnetic flux is known as magnetic circuit, As an electric emf is necessary to cause the flow of current in an electrical circuit, similarly magneto motive force (mmf) is required to create the magnetic flux in the magnetic circuits, As the current flowing in an electrical circuit depends upon the emf and resistance of the circuit, similarly the magnetic flux or number of lines of force produced in any magnetic circuit depends upon the mmf acting in the circuit and reluctance of the circuit, Electric circuit resistance causes heat to generate resulting in the wastage of energy, there is no wastage of energy due to reluctance in magnetic circuits.
