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.

The Danish physicist Hans Christian Oersted was lecturing one day in 1820 on the possibility of electricity and magnetism being related to one another, and in the process demonstrated it conclusively by experiment in front of his whole class! Magnetism happens when materials exert attractive or repulsive forces on other materials. The direction of current and the direction of magnetic field are at right angles to each other. Magnetism refers to the magnetic properties of objects that have the tendency to attract or repel each other. When opposite poles of a magnet are close to each other, there is a force of attraction between them. MCQ on Magnetism and Electromagnetism - Set 09 MCQ Electromagnetism Edit Practice Test: Question Set - 09. When the button is pushed the circuit is completed allowing current to flow, this magnetises the electromagnet causing it to attract the iron armature, this then causes the hammer to strike (they are connected).
