To calculate the force on a wire carrying a current at right angles to a magnetic field, use the equation: force on a conductor carrying a current = magnetic field strength × current × length A 50 cm ...

To investigate, describe and recall how the strength of the magnetic field close magnetic fieldA region around a magnet or around a wire carrying a current, where a magnetic force is experienced.

Permanent magnets play a crucial role in medicine due to its field strength, tunability of field and gradient distributions, as well as practical implementation. In a new study published in KeAi ...

Gas-giant planets orbiting close to other stars have powerful magnetic fields, many times stronger than our own Jupiter, according to a new study by a team of astrophysicists. It is the first time the ...

Signals from star-planet interactions tell of strong magnetic fields in 'hot Jupiters'. Gas-giant planets orbiting close to other stars have powerful magnetic fields, many times stronger than our own ...
