Abstract
The present invention provides a method and an apparatus for measuring a force (which will be referred to as surface force) acting between two material surfaces. A surface force measuring method includes moving an object () toward a probe () until the probe () is adsorbed to the object (), then applying a load from an electromagnetic-force generator () to a supporting member () in a direction as to separate the probe () from the object () while gradually increasing an electric current supplied to the electromagnetic-force generator (), obtaining a value of the electric current supplied to the electromagnetic-force generator () when the probe () is separated from the object (), and converting the value of the electric current into a surface force acting between the probe () and the object ().
