Hi there,
As we know that force can change size,shape of an object as well we also know metal are generally hard so whn we apply force on wire to move back nd fourth it contracts and give heat as a result..

Wire get heated up when it is bent back and fourth because the metal is being disfigured.

  • Flexible deformation in metals involves bodily reshuffling of some of the bonds between neighboring atoms in the metal's crystal lattice.
  • As bonds are rearranged, shifted, or broken, some of that energy goes to causing vibrational motions in the atoms themselves.

This is why wire gets heated up when bended.
