Magnets and electromagnets quiz

In this quiz, you will see that, In our world today,  magnets are essential in electronic technology. Magnets are very useful, fun, and even a little mysterious. Magnets repel as well as they attract. The science of magnetism is tied to the modern science of electricity but has been recognized for many years now and In industrial society, magnets used in electrical generators convert mechanical energy to electricity and vice versa. This particular quiz is bent on helping you in preparation for your Exams, or tests on Magnets be it GCE, GCSE, or SATs. 

Magnetism in simple words is the power of a material to attract. It also refers to the attraction to iron and other metals in electric currents and magnets. Different kinds of magnetism cause some magnets to attract, while others cause them to repel.  We, therefore, need to take note here that magnetism is a very important topic and because we use it to create electrical energy, it does help in certain appliances to engineers and technicians.  Most of the energy that we use today is produced from rotating magnets. Some very essential properties of magnets are attractive, made up of 2 poles, also repel.
 An electromagnet any magnet that runs on electricity. Unlike permanent magnets, the strength of electromagnets can easily be changed, by changing the amount of electric current that flows through them. We realize that the poles of an electromagnet can even be reversed by reversing the flow of electricity. Moving charges create magnetic fields, so when the coils of wire in an electromagnet have an electric current passing through them, the coils behave like a magnet.  

To summarize, Magnets and electromagnets are used in a wide range of fields, like engineering, electrical engineers use magnets in most of their  Construction where almost all electrical gadgets, equipment, and machines are done using the properties of magnetism, like in transformers, electrical rotating machines.
