Electromagnetic induction | Radiology Reference Article | Radiopaedia.org
Electromagnetic induction is the induction of electric current via changing magnetic fields. Magnetic fields are generated by moving charges (equivalent to electrical current). Ampere's law or Fleming's right-hand rule determines the magnitude and direction (i.e. clockwise or anti-clockwise) of the magnetic field with respect to the direction of the flow of …
