Induction

4.0K
An emf is induced when the magnetic field in a coil is changed by pushing a bar magnet into or out of the coil. emfs of opposite signs are produced by motion in opposite directions, and the directions of emfs are also reversed by reversing poles. The same results are produced if the coil is moved rather than the magnet—it is the relative motion that is important. The faster the motion, the greater the emf. Additionally, there is no emf when the magnet is stationary relative to the coil.

Paramagnetism

2.5K
Paramagnets are materials with unpaired electrons that possess a finite magnetic moment. In the absence of a magnetic field, these moments are randomly oriented, and thus the net moment is zero. Under an external field, a torque acting on the moments tends to align them along the field's direction. However, the random thermal motion of electrons produces a torque opposite to the external field and tries to disorient the moments. These two competing effects align only a few moments along the...

Ferromagnetism01:31

Ferromagnetism

2.4K
Materials like iron, nickel, and cobalt consist of magnetic domains, within which the magnetic dipoles are arranged parallel to each other. The magnetic dipoles are rigidly aligned in the same direction within a domain by quantum mechanical coupling among the atoms. This coupling is so strong that even thermal agitation at room temperature cannot break it. The result is that each domain has a net dipole moment. However, some materials have weaker coupling, and are ferromagnetic at lower...

Area of Science:

  • Materials Science
  • Biomedical Engineering
  • Electromagnetism

Background:

  • Conducting polymers (CPs) exhibit magneto-thermal conversion properties when exposed to alternating magnetic fields (AMFs).
  • This heating effect is primarily driven by induced eddy currents within the material.
  • The efficiency of heating depends on factors like AMF characteristics and CP properties.

Purpose of the Study:

  • To investigate magnetic induction heating in conducting polymers under AMFs.
  • To explore the control of thermal fields in CPs for specific applications.
  • To demonstrate the potential of CP-based magneto-thermal conversion in biomedical fields.

Main Methods:

  • Experimental measurements and numerical simulations were used to analyze magneto-thermal conversion.
  • Various fabrication methods were employed to create CP films and aerogels.
  • A conducting polymer aerogel-based self-adaptive heat patch was designed and tested.

Main Results:

  • Eddy currents induced by AMFs are responsible for magneto-thermal conversion in CPs.
  • CP heating is influenced by AMF parameters and intrinsic material properties.
  • Localized skin heating was achieved using the developed heat patch.
  • Demonstrated thermal ablation of tumor cells and promotion of neuronal differentiation.

Conclusions:

  • Conducting polymers offer a viable platform for AMF-induced localized heating.
  • CP-based magneto-thermal conversion has significant potential in biomedical applications, including cancer therapy and tissue engineering.
  • Self-adaptive heat patches can be developed for targeted therapeutic interventions.
