Larger coils require more space and can limit design choices for manufacturers who want to produce small portable devices. The size limitations also hinder retrofitting older devices with larger coils, as they have been designed with specific dimensions in mind.
This limitation has led manufacturers to develop alternative solutions, such as miniaturized versions of bigger coil technology or utilizing multiple smaller-sized ones instead. While bigger coils offer numerous advantages over smaller ones in certain applications, such as motors and generators, their drawbacks cannot be ignored.
The cost of producing larger components and sizing constraints limit its use cases. As technology advances and demand increases, it remains uncertain if we will see an increase or decrease in usage over time. Still, regardless, we will always need engineers who can balance these factors when designing new products that require them.
Niche Subtopics: Applications where bigger coils excel
Magnetic Resonance Imaging (MRI)
One area where bigger coils have a significant advantage is in Magnetic Resonance Imaging (MRI). MRI machines use large magnetic fields to align the spin of hydrogen atoms in the body, emitting signals to create detailed images of internal organs and tissues. Larger coils are necessary to create stronger magnetic fields and, thus, better image quality.
Additionally, larger coils can help reduce image noise, which can occur when the signal-to-noise ratio is low due to a weaker magnetic field. As such, bigger coils are an essential component of modern MRI technology.
Explanation of why MRI machines require large magnetic fields to function effectively
The reason why MRI machines require large magnetic fields is due to the nature of how they work. Hydrogen atoms in the body have a property called spin, which allows them to behave like tiny magnets.
When placed in a strong external magnetic field, these atoms align their spins with that field direction. A pulse of radiofrequency energy is then applied, temporarily causing some of the hydrogen atoms’ spins to flip perpendicular to the applied field.
When this radiofrequency pulse stops, the hydrogen atoms return to their original state and release energy as they do so. This energy release creates signals that can be detected and used for creating detailed images.
Conclusion
Using larger coils in electronic devices offers many advantages across different applications, such as increased power output and improved efficiency, where size isn’t an issue or where larger sizes are required, like MRI machines for better imaging quality, despite some associated disadvantages like increased cost and size limitations. The debate over whether bigger coils are better rages on among electronic enthusiasts, but for now, it’s safe to say that bigger coils are here to stay, and they will continue to play an essential role in developing future technologies.
