This heat drives convection cells within the liquid core, which keeps the liquid metal moving through the magnetic field. The so-called Coriolis force also plays a role in sustaining the ...

To calculate the force on a wire carrying a current at right angles to a magnetic field, use the equation: 2 A flows through a 50 cm wire. Calculate the force acting on the wire when it is placed ...

It has an invisible magnetic field. Only certain materials, such as iron, feel a magnetic force. Permanent magnets can come in lots of different shapes and sizes. Bar magnets and horseshoe magnets ...

What is Magnetic Force Microscopy (MFM)? Magnetic Force Microscopy (MFM ... MFM is based on the detection of magnetic interactions between a magnetized probe tip and the magnetic fields emanating from ...
