Discover top 7 world’s most powerful man-made magnets that reshape modern physics
The article highlights seven of the world’s most powerful man-made magnets, emphasizing their critical role in advancing modern physics by enabling scientists to probe extreme material and quantum phenomena. These magnets, housed in leading research facilities globally, generate extraordinarily strong magnetic fields—far beyond everyday magnets—using advanced materials, complex cooling systems, and vast electrical power. Some operate continuously, while others produce intense, short pulses, each serving unique experimental needs. Key magnets include the 100-tesla pulsed magnet at Los Alamos National Laboratory, which holds the record for the strongest non-destructive magnetic field, producing brief but extreme pulses to study quantum behaviors. The National High Magnetic Field Laboratory’s 45.5-tesla hybrid magnet generates the strongest continuous field by combining superconducting and resistive technologies, enabling long-duration experiments. China’s 42-tesla resistive magnet is notable for achieving the highest field from resistive coils alone, consuming immense power and requiring extensive cooling. China also briefly held the continuous field

Microsoft-backed startup Veir is developing superconducting electrical cables designed to address the rapidly increasing power demands of data centers, which have surged from tens to 200 kilowatts per rack and are projected to reach up to a megawatt in the near future. Traditional low-voltage copper cables become bulky and inefficient at these scales, but Veir’s superconducting cables can carry up to 3 megawatts of low-voltage electricity while occupying 20 times less space and transmitting power five times farther. These cables operate at extremely low temperatures (–196˚C) using liquid nitrogen cooling to maintain superconductivity, enabling zero energy loss. Veir has adapted its core superconducting technology, initially developed for long-distance power transmission lines, to meet the specific needs of data centers. The company has built a simulated data center in Massachusetts to demonstrate the technology and plans pilot deployments in operational data centers next year, aiming for a commercial launch in 2027. The startup acts as a systems integrator,

The article from CleanTechnica highlights the critical but often overlooked role of refrigerants in the efficiency, cost, and environmental impact of HVAC systems, including air conditioners and heat pumps. Refrigerants are essential chemical compounds that enable cooling and heating functions, yet many systems operate with improper refrigerant levels. A common issue is undercharging, where systems have less refrigerant than designed, sometimes by about 15 percent, which can occur even at installation due to improper adjustment for specific configurations like longer piping. This undercharging leads to reduced cooling performance and increased energy consumption. Over time, refrigerant leaks caused by aging equipment, corrosion, and vibrations further degrade system efficiency. Residential HVAC systems can lose 5–11 percent of their refrigerant annually, resulting in a significant drop in the coefficient of performance (COP). Even a 10 percent refrigerant loss can reduce system efficiency noticeably, increasing energy bills by $72–$144 during summer months. Larger losses above 20 percent cause steep performance declines and soaring

BYD recently announced that its Yangwang U9 Xtreme hypercar set new records, including a top speed of 308.37 mph (approximately 496 km/h) and an electric vehicle (EV) lap record at the Nürburgring. These achievements not only provide BYD with significant bragging rights but also challenge the dominance of traditional fossil-fueled hypercars. The U9 Xtreme’s performance is powered by a 2220 kW (2977 hp) motor system paired with an 80 kWh battery featuring an advanced double-layer cooling structure that enables a 30C discharge rate, contributing to a 133% increase in power and a 40% improvement in heat exchange efficiency. The technological advancements in cooling and power electronics, including the use of silicon carbide (SiC) components, may have broader implications beyond the hypercar segment. BYD’s innovations could enhance the reliability and efficiency of mainstream electric vehicles, especially in extreme heat conditions, and potentially improve charging

Panasonic’s Living Appliances and Solutions Company celebrated the 70th anniversary of its pump business in 2025, marking a significant milestone since its inception in 1955 with home well pumps. Over the decades, Panasonic has expanded its pump applications to include built-in pumps for water heaters, heating appliances, and bathroom equipment, contributing to energy efficiency and environmental friendliness. With cumulative shipments surpassing 53 million units, Panasonic pumps are widely used not only in its own products but also by various manufacturers globally. In response to the growing demand for efficient cooling solutions in data centers—especially driven by the rise of AI technologies and the increasing heat generated by CPUs and GPUs—Panasonic has developed a next-generation cooling water circulation pump tailored for data center cooling systems. This pump integrates advanced simulation technologies to improve performance by 75% (from 40 to 70 L/min) while maintaining a compact size suitable for installation within Coolant Distribution Units (CDUs). Key features include high efficiency, compact housing for
