Magnetic locking systems and interactive challenges showcase the incredible strength and precision of magnets. From securing ...

What is Magnetic Force Microscopy (MFM)? Magnetic Force Microscopy (MFM) is a scanning probe microscopy technique that allows the imaging and characterization of magnetic properties of materials at ...

How a Generator Works When an electric current flows through a wire, it generates a three-dimensional magnetic force field around the wire, similar to that surrounding a bar magnet. Magnets are ...

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 ...

Currently, these are the most promising concepts for future fusion energy plants. Both reactor types make use of the fact that charged particles react to magnetic forces. Strong magnets in the ...
