Tools and Setups for Experiments with AC and Rotating Magnetic Fields
Ponikvar, D.
European Journal of Physics, v31 n5 p1255-1266 Sep 2010
A rotating magnetic field is the basis for the transformation of electrical energy to mechanical energy. School experiments on the rotating magnetic field are rare since they require the use of specially prepared mechanical setups and/or relatively large, three-phase power supplies to achieve strong magnetic fields. This paper proposes several experiments and describes setups and tools which are easy to obtain and work with. Free software is offered to generate the required signals by a personal computer. The experiments can be implemented in introductory physics courses on electromagnetism for undergraduates or specialized courses at high schools. (Contains 17 figures.)
