Goals• To find and design a solenoid coil which can

produce higher H-field (1000 – 3000A/m) at 13.5Mhz.– Current– Materials (copper wire, size, radius, etc.)– Radius Change: is the radius change per turn of

helix/coil– Pitch: is the distance between helix/coil turns– Turns: is the number turn of the helix/coil
