Both solenoid and toroid are coils made of conductor wires and are used in a variety of electrical and electronic circuits to produce a magnetic field with help of electric current. The fundamental difference between solenoid and toroid is that the solenoid is a cylindrical shaped electromagnetic coil used to generate a magnetic field outside it, while a toroid is a circular (doughnut) shaped electromagnetic coil used to produce a magnetic field within itself. In this article, we will learn the important differences between solenoid and toroid, but before discussing the differences, let us first have a look into ... Read More

Copper coil and aluminium coil are two important components in air conditioning, heating, ventilation systems. Also, copper coils and aluminium coils are widely used in several different industrial applications where highly efficient heat transfer is required. The fundamental difference between copper coil and aluminium coil is that the copper coil is made up of copper tubing which is wound in a coil shape of multiple turns, while the aluminium coil is made up of aluminium tubing which is wound in a coil shape of multiple turns. In this article, we will discuss all the important differences between copper ... Read More
