Scientists say the discovery of this dynamo-like mechanism could solve the mystery of so-called "low-field magnetars." Magnetars are neutron stars with the universe's most powerful magnetic fields ...

which keeps the liquid metal moving through the magnetic field. The so-called Coriolis force also plays a role in sustaining the geomagnetic dynamo. Our planet's spinning motion causes the moving ...

increasing the rate of rotation increasing the strength of the magnetic field increasing the number of turns on the coil The diagram shows four different positions of the coil in a dynamo ...
