Magnetic force can overcome gravity. That’s why this magnet can hover in mid-air. Electrostatic force also attracts and repels objects. Rubbing the balloon on another surface creates a small ...

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 ...

they deliver more gauss (the unit of magnetic induction) than a neutron star. “Those fast-moving positive charges should generate a very strong magnetic field, predicted to be 1018 gauss ...
