N2  - Polyvinylidene fluoride (PVDF) is a flexible polymer with strong piezoelectric  properties, making it highly suitable for applications like energy harvesting and sensors.  However, obtaining the desired β-phase in PVDF, which is critical for enhanced  piezoelectricity, is challenging due to its tendency to crystallize in the α-phase. This study  addresses this problem by investigating the effects of an applied magnetic field using  Helmholtz coils and the addition of Fe₃O₄ nanoparticles during electrospinning to  promote β-phase formation. PVDF nanofibers were synthesized using the electrospinning  method, with variations in the use of magnetic fields and Fe3O4nanoparticles. Structural  and piezoelectric properties were analyzed using Fourier Transform Infrared  Spectroscopy (FTIR) and X-Ray Diffraction (XRD). Results showed that a magnetic field  enhanced β-phase formation and aligned nanofibers, improving piezoelectric properties.  Similarly, Fe3O4 nanoparticles contributed to β-phase formation by facilitating  crystallization. However, combining the magnetic field with Fe3O4 resulted in reduced  improvements due to interference effects. The study concludes that using the magnetic  field and nanoparticles separately achieves the best results, providing valuable insights  for optimizing PVDF nanofibers for advanced piezoelectric applications
