6 Hidden Uses of Magnets in the Olympics

As we begin to dive into another exciting Olympics, here at Magnet Store, we are fascinated by how the power of magnets is used in this much-loved sporting event. Although it might not be obvious, magnets play a crucial role not only in the competitive events themselves but also in various supportive technologies and equipment used throughout the games. Here are six fascinating facts about how magnets are cleverly integrated into the Olympics.

1. Curling Sensors:

Magnets are often used as a key component in sensor systems, and in recent years, this technical advancement has been brought into the Olympic game of curling. Magnetic-powered devices embedded in the handles of the stones, along with magnets placed below the ice, ensure compliance with the rules by detecting when a player has let go of the handle. These devices transmit the results, making them visible to players and spectators through small lights on the stones. If the curler hasn’t released the stone in time, the green lights turn red, signaling a fault. Thus, magnets play a vital role in maintaining fairness in curling by acting as an additional referee, ensuring every throw is within the rules.

2. Taekwondo Points System:

In Rio de Janeiro, taekwondo’s points system was upgraded with the use of magnets. These magnets interact with sensors in the athletes’ protective gear to detect valid strikes. When a magnetised footpad comes into close proximity with or contacts the protective gear, it triggers the sensor system, confirming a legitimate hit by detecting changes in the magnetic field. This ensures that only appropriately forceful and accurately targeted strikes, typically made with the correct part of the foot, are scored. This magnetic technology improves the accuracy and objectivity of scoring in Taekwondo, providing real-time data to judges. The system used at the Rio 2016 Olympics, and in many other international competitions, ensures fair and precise scoring.

3. Archery:

In Olympic archery, some bow models integrate magnets into stabilisers, accessories attached to the bow to improve stability and reduce vibrations during and after the shot. Stabilisers are designed to balance the bow and dampen vibrations. Magnets within the stabiliser or vibration-damping system absorb and minimise these vibrations, enhancing the bow’s stability and the archer’s accuracy. Additionally, the placement and configuration of magnets help adjust the bow’s weight distribution. This balance is crucial for maintaining a steady aim and consistent shooting form. By adding magnets, archers can fine-tune their equipment, making it easier to hold steady, especially during windy conditions or long shooting sessions.

4. Prosthetics and Equipment for Paralympic Athletes:

Paralympic athletes rely on advanced prosthetics and wheelchairs, many of which incorporate magnets to enhance functionality and performance. Prosthetic limbs often use magnetic connectors to improve attachment and alignment, allowing athletes to quickly and securely attach different components, such as various types of feet or hands, depending on the sport. This versatility is crucial for athletes who need to adapt their prosthetics for various activities. In wheelchair racing, magnets can be used in the construction of wheels and alignment mechanisms. Magnetic bearings reduce friction, allowing for smoother and faster wheel rotations, while magnetic alignment systems ensure the wheels are perfectly positioned for stability and control. These innovations enable Paralympic athletes to achieve peak performance and compete at the highest levels.

5. Accessible Uniforms:

Magnets are making the Olympics more inclusive and accessible through the use of magnetic fasteners in athletic uniforms. The Australian Olympic team has notably adopted magnetic fasteners in their Paralympic uniforms, replacing traditional buttons and zippers. This innovation allows athletes with disabilities to dress independently and comfortably, eliminating the need for fine motor skills that can be challenging for some individuals. Magnetic fasteners are easy to use and secure, ensuring that uniforms remain intact during intense physical activity. This development not only enhances the practicality of athletic wear but also empowers athletes by providing them with greater autonomy. By incorporating magnets into their uniforms, the Olympics are taking significant steps toward inclusivity, ensuring that all athletes can compete with confidence and dignity.

6. Injury Diagnostics:

Competitive sports can often push athletes to their physical limits, making medical diagnostics essential. One common machine used for diagnosing injuries is the MRI (Magnetic Resonance Imaging) machine, which relies on powerful magnets. MRI machines use strong magnetic fields and radio waves to create detailed images of the body’s internal structures. This non-invasive technology is particularly valuable in diagnosing sports injuries, as it can clearly differentiate between various soft tissues such as muscles, tendons, and ligaments, and highlight abnormalities in joints and bones. By providing high-resolution images, MRI allows doctors to accurately identify issues like tears, strains, and inflammation, which are common in athletes. This detailed information is essential for developing effective treatment plans, ensuring that athletes receive the best care possible to recover quickly and safely.

Final thoughts

Magnets may be small, but their impact on the Olympics is mighty. From ensuring fairness in curling and accuracy in taekwondo scoring to enhancing the performance of Paralympic athletes and aiding in injury diagnostics, magnets play a crucial role behind the scenes. These hidden uses of magnets highlight their versatility and significance in making the games safer, fairer, and more inclusive for all athletes. As we watch the thrilling events unfold, let’s take a moment to appreciate the incredible technology that helps athletes perform at their best and keeps the spirit of the Olympics alive and thriving. So next time you see a curling stone’s lights turn green or witness a flawless taekwondo strike, remember the silent power of magnets working tirelessly to support the games we love.
