Question

A 4.0-cm-diameter loop with resistance 0.17 12 around a 2.0-crn-diameter solenoid. (Figure 1) The solenoid is 11 cmn long, has 100 turns, and carries the current shown in the graph (Figure 2). A positive current is cw when seen from the left. Part A Find the current in the loop at t = 0.5 8. Express your answer as an integer and include the appropriate units. I(0.5) = OA Previous Answers ✓ Correct Part B Find the current in the loop at t = 1.5 S. Express your answer to two significant figures and include the appropriate units.

Answer 1

given that dlaraeter of the loop d= 4 x 102m Resistance of the loop R = 0.17 diameter of the Solonoid d = 2x10-2m The length of the solenoid la 12x15²m The nom of terms of solonoid N = 100 We know etic field at center of solenoid Be Mo (l/JxI magnetic flan a= BA . ☆ ( Å (B4)) ať st I MO N X In Iin = Monare da Re Tu given t=a.5s, change in current de L = oA Ein = MONTI2 Re xo Lia OA

t=1.5, t=1151 ano change in current dot 40A rady = 2x102 = 1x102 Ii = MOXNXT 12 - X 40 Re unX10*x100xTTX (lx102) ? - 840 o.178 (11x102) = 2.11x106x40 In = 84.4 MA tz 2.5 there is no change in Current =0 So Iin z MONIT – x 0 RL Fin= oA Please rate my Answer Thanku.
