Volumen mit einer Grundfläche (Spulenfläche) von
L = 40 mm und B= 10 mm und einer Höhe H=5 mm gefüllt. Bei einem Dauermagneten gleichen Volumens wird ein B = 150 mT gemessen. Wie gross ist das Magnetfeld der Spule? LDraht = 9.68 m NSpule = 121 B = 12.6 mT RSpule = 1.37 Ω Imax = 0.45 A USpule = 0.6 V L = 1.47 mH |
