Hace 3 días · Figuring out how the sun’s magnetic field works will help scientists improve the forecasting of space weather, which dazzles night sky watchers but can disrupt GPS and communication satellites.
Hace 1 día · Actuators are devices that convert an input signal — such as light, heat or magnetism — into mechanical energy. Soft actuators, which are encased in pliable, rubbery materials, can safely interact with biological tissues and possess unique mechanical properties that make them ideal building blocks for surgical robots, wearable devices, augmented reality gadgets and human-machine interfaces.
Hace 1 día · DOE STEM. Magnetically Drawn to Science. In the ever-evolving landscape of particle accelerators, researchers at the U.S. Department of Energy's Thomas Jefferson National Accelerator Facility constantly seek innovative solutions to enhance efficiency and reduce costs. Enter Christian Cagnino, an astrophysics major interning through the DOE’s ...
Hace 1 día · Solar storms and geomagnetic storms are closely linked to electricity and magnetic fields. When a solar storm induces currents in Earth’s magnetosphere, these can overwhelm the power grid ...
Hace 4 días · The magnetic field is an abstract entity that describes the influence of magnetic forces in a region. Magnetic field lines are a visual tool used to represent magnetic fields. They describe the direction of the magnetic force on a north monopole at any given position.
Hace 3 días · Maglev (derived from magnetic levitation) is a system of rail transport whose rolling stock is levitated by electromagnets rather than rolled on wheels, eliminating rolling resistance. [1] [2] [3] Compared to conventional railways, maglev trains can have higher top speeds, superior acceleration and deceleration, lower maintenance costs, improved gradient handling, and lower noise.
Hace 4 días · If placed at an angle in a magnetic field, a current loop will experience torque and rotate. The propensity of a current distribution to experience torque in a magnetic field (and also create its own magnetic field) is characterized by its magnetic (dipole) moment.
