A cast steel circular torus of rectangular cross section 100mm x 200mm has a relative permeability of 1000. HINT After 15s, the normal to the coil is 60 with the magnetic field. The wire (below) is placed under a compass needle and electrons are flowing from A to B., A:Since the electorns are flowing from A to B, current will flow from B to A. A at loop of wire consisting of a single turn of cross-sectional area A=8.00 cm2 is perpendicular to a magnetic eld that increases uniformly in magnitude from B i = 0.500 T to B f = 2.50 T in 1.00 s. What is the resulting induced current if the loop has a resistance of R=2.00. What was the average change in temperature per hour? A circular coil of radius 1 0 c m, 5 0 0 turns and resistance 2 is placed with its plane perpendicular to the horizontal component of the earth's magnetic field.
