hi, i would like some advice on the below theoritical circuit. the circuit has to give an output in the form of magnetic pulses using a electromagnet, so i have thought of employing a counter circuit connecting the output to a power amplifier and finally to a electro magnet, now when the counter finishes one cycle it would give one impulse which would be amplified and fed to the electromagnet so magnetic field can be produced in the desired pulse mode. now my doubts are . . which material to use so i get the optimum intensity of the field, can i use a trigger circuit between the counter and amplifier, how to calculate the field equations for the same.
