Experiment and Computation on a Solenoid Electromagnet

A solenoid electromagnet was studied by finite element analysis method,the force characteristics of the electromagnet and its magnetic field distribution under the different displacements,the current of the electromagnet turns and the frame parameters were analyzed.The testing set for the electromagnet force characteristics was designed in order to prove the computing results.The dynamic and static states of the electromagnet can be measured by the set.The results of the theory analysis were compared with the experimental results in the diagram and the reason of the different of the both was analyzed.A new electromagnet was designed according to the above result.It is shown in the diagram that the theory results agree more with the experimental results on the new electromagnet.
