Discover how to build a simple electric train using just a copper coil, an AA battery, and disc magnets in this step-by-step ...

Hybrid magnet for "neutron scattering" experiments to be built. The planned magnet will produce a magnetic field between 25 tesla and 30 tesla -- more than half a million times stronger than the Earth ...

A permanent magnet changes the flux through coil, generating a voltage that can be read by an analog voltmeter (you can pretend it's a galvanometer). Connect the voltmeter to the coil or to the DAQ ...

Placing each of these four H-coils at different distances to the surface of the specimen "enables us to evaluate the influence of the position of the H-coil on the measurement accuracy of magnetic ...

We’ve all seen huge magnets do really incredible, showy things in TV and film. They helped to get Walter and Jesse out of a pinch in Breaking Bad, they made Bender Bending Rodriguez sing “She’ll Be ...

In Hefei, China, physicists switched on a new machine that pushed magnetic fields to record strength. As the device powered up, it held a magnetic field more than 700,000 times stronger than Earth’s ...

Built with both traditional and novel superconducting materials, the magnet reached a field of 27 teslas on June 5 in a test that exceeded designers’ expectations. The magnet is a smaller version of ...

The strongest superconducting user magnet in the world currently has a field strength of 23.5 tesla. When this ambitious project is completed in 2017, the strongest superconducting magnet on the ...
