High frequency AMF generator was set up and studied for different coils. Fields were measured in center line of coil at distance 20cm. Spectra of EM field was studied. Phantoms with different electric conductivities for further experimental research were generated using water and polymer agarose. Cylindric tube is filled with polymer agarose solution. Tube is placed in circuit with 900K resistor in series and source generator. Measuring voltages using oscilloscope we can calculate conductivity of the solution. Using this method two phantoms were generated with 0.867 S/m and 0. 624 s/m conductivities. EM code was added to the program package to study EM problems. Namely: 1. Calculation and visualization of eddy Electric field in electrostatic limit. 2. Calculation of point SAR(Specific Absorption Rate). 3. Visualization of point SAR.
