This persnickety number determines the strength of magnetic fields. It figures in everything from motors and generators to ...

Magnetism is a natural force, one that works at a distance. Magnets get their force from magnetic fields created by the atoms within the metal. Magnets are useful for things like turbines we use ...

The San Diego-based company General Atomics celebrated the shipment of a device it claims will make nuclear fusion possible. The world's most powerful magnet has been sent to France, where an ...

Here, a moving magnet induces a current in a stationary conductor, producing a repulsive force that increases with the speed of the moving magnet. The last category, called spin-stabilized levitation, ...

Eventually, the blob of molten material beneath Canada split in two and the stronger one slowly shifted toward the blob ...

Each of these duly orients itself in the magnetic field, revealing how the direction of the magnetic force varies from place to place. Related: ...

Magnetic force microscopy (MFM) is a scanning probe technique for nanoscale mapping of magnetic properties, crucial for characterizing magnetic materials.

Magnets have practically become everyday objects. Earlier on, however, the universe consisted only of nonmagnetic elements and particles. Just how the magnetic forces came into existence has been ...

What does the force near a magnet even look like? One way to find out is to put two magnets near each other and measure the force at different distances. Here is the setup I used.

Record-setting solar flare images show ultra-thin magnetic loops, a discovery that could sharpen predictions of space weather threats.
