Introduction to Electromagnetism
When scientists discovered in the 20th century that electricity and magnetism were not two separate topics and that they can be combined it led to the revolutionary discovery of electromagnetism. This discovery transformed both engineering and our daily lives. If you are looking to enhance your understanding of electromagnetism then you have come to the right place. This free online course will give you a comprehensive understanding of electromagnetism. It kicks off by looking at the magnetic effect of electric current and the various methods available for magnetization. You will be able to analyze solenoids and how to find the direction of an electrically induced magnetic field. Detailed illustrations and formulas will be provided to ensure that key concepts such as hysteresis magnetomotive forces and magnetic shielding can be properly understood. A description of toroids and factors that affect the strength of electromagnets will also be provided.As the course moves on some other key components of electromagnetism are also discussed. The phenomenon of magnetically induced electricity is a crucial component of electromagnetism. An analysis of the various methods used in inducing EMF (electric and magnetic fields) along a conductor will be carried out along with an explanation of the laws of electromagnetic induction. Faraday’s laws of electromagnetic induction Lenz’s law and Fleming’s right-hand rule will be explained along with illustrations and key formulas. These laws will not only help you understand how EMF is induced but also identify the direction and magnitude of that induced EMF along a current-carrying wire or coil. Next you will discover eddy currents and the methods used to reduce them. Important instruments are used in experiments of electromagnetism and will be the focus of the next part of the course. An explanation of what a galvanometer ammeter and voltmeter are is provided. Their key functions and construction methods will be the main discussion points.As the course moves towards its final section your focus will shift to magnetically induced forces on a current-carrying wire. An explanation of Fleming’s left-hand rule which is used to find the direction of the force on a current-carrying wire will be provided. Another critical component is the effect of torque on a rectangular current loop placed in a uniform magnetic field. The course will guide you through this key component along with a discussion of forces between two current-carrying conductors. As mentioned earlier the discovery of electromagnetism was revolutionary in the field of science. From day-to-day use in doorbells or audio earphones to the creation of life-saving gadgets such as MRI machines electromagnetism changed the world that we live in. The concepts of electromagnetism form a crucial part of anyone’s understanding who is either looking to satisfy their curiosity or deciding to make a career out of them. In either case this online course on electromagnetism has you covered so enrol today.
