Magnetic components are a crucial part of keeping nearly every type of modern electronic device functional. They can be found just about everywhere, providing essential functions such as filtering, energy storage, and power conversion, and play a major role in driving the development of more efficient and more compact electronic systems. Without magnetics, much of the technology that we have today wouldn’t be possible.
A Quick Guide to Magnetic Component Basics
Magnetics are materials that exhibit attraction and repulsion to other materials, and generate a magnetic field, much like a small force field. This field can change the direction of an electric current, converting magnetic energy into electrical energy and back again depending on how the magnetic field is manipulated. The strength and direction of the magnetic field can be adjusted to meet specific requirements for different applications.
Using Magnetics for Power Conversion
One of the major benefits of magnetic components is their ability to convert different types of energy. They can be found in conjunction with coils in electric motors. When the coils are energized, they create a magnetic field that interacts with that of the actual magnetic component. The magnet then generates a rotational torque that causes the motor’s rotor to spin, essentially turning electric energy into mechanical force. Magnetic components are essential for transformers as well, which convert electrical energy into very specific voltages. These are crucial components for ensuring the safety of an electrical device and protecting it from damage.
Managing Electric Currents
Magnets are used to create electric currents all the time, whether that’s through wrapping a magnet around a wire, or winding a wire around a magnet. These highly precise windings can then be used to carefully manage the direction and strength of the current, as well as direct them towards the rest of the system.
Magnetic Storage Cores
Magnetic cores are a common find in all different types of energy storage applications, as they can be configured in a variety of ways. These types of magnetic components can be used to harvest and convert energy, like in conductors and inductors. They’re also important for transferring energy across different pieces of equipment, and storing energy within a device as well, ready to be converted at any time.
