Abstract
This paper proposes a new method for investigating the elastic properties of bio-relevant films, based on the study of object deformation under the action of a steel ball, used as an intendor, placed in a magnetic field. Varying the distance between the magnet and the steel ball allows varying the amount of the applied force in a wide range, which opens up a great potential of the proposed method for studying a large class of biologically relevant objects. The capabilities of the proposed method are demonstrated by an example of determining Young's modulus of hydrogel films of different stiffness, made on the basis of gelatin.
