Assignment #5 PHYSICS 354/4-01 ELECTRICITY & MAGNETISM II April. 2010 Assignment #5 Page 1 of 2 Solution to Assignment # 5 00 3 . 7.8, p (a) Magnetic field is produced by the long wire with current I to the right. = = = Φ + = a s s s o s d a s I a d B π μ 2 + s a s n Ia o l 2 Both B and = , s ad a d out of page (b) Loop pulled away from wire at a speed v . dt ds s a a s s Ia s a t a s s Ia s a s n t Ia t o o o + = + + - = + - = Φ - = 2 2 1 2 2 l E v a s s Ia o + = 1 2 2 . Since the flux is out of the page and decreasing, the direction of the induced current is such as to compensate the loss of flux. So it flows counter-clockwise to produce more flux out of the page. (c) Pulling the loop to the right does not cause any flux change. 0 = E 00 3 . 7.11, p The falling aluminum square loop has sides b , and the total resistance
