In figure a the rectangular loop is pushed into the magnetic field which point inward. In figure b the north pole of the magnet bar is being inserted into the coil. In figure c the coil of wire moving out of magnetic field. In Figure D the solenoid being pulled away from the loop shown. In what direction of induce current occur in rectangular loop , coil through resistor R, in the loop 2. Part of the singular rectangular loop of wire is situated inside the region of magnetic field B= 0.55 T into the paper. The total resistance of the loop is 0.23 Ω . Calculate the force required to pull the loop from the field to the right at constant velocity 3.4 m/s. Neglect the gravity.(Ans. F = 0.55 N) *The perpendicular magnetic field passing through a 10 turn coil of radius 50 mm. The field is increased from to 18 T in 3 s. If the resistance of the coil is 2 Ω, what is the magnitude of induced current. what is the direction of the current in the coil. (Ans 0.235 A. counter clockwise.) A coil of5.0 cm in diameter has 20 turns and a resistance of 0.5Ω. A magnetic field perpendicular to the coil is B= 0.02t + 0.01t2, where b is in tesla and t in seconds. Find induce current in the coil at t = 2 s. (Ans. I = 47.1x10-4 A) A 100 turns of coil 2.0 in diameter is at rest in a horizontal plane. A uniform magnetic field 600 from vertical is increasing from 0.5 T to 1.5 T in 0.6 s. What is induced current in the coil which resistance 0.5Ω. What is the direction of current. A 4.0 cm diameter of single coil loop with resistance 0.1Ω surrounds a 2.0 cm in diameter solenoid. The solenoid is 10 cm long, has 100 turns and carries a current show in the diagram. The current of solenoid is increased from 2 A to 10 A in 0.3 s. What is the magnitude of induced current in the coil, and the direction. (Ans. I = 10.7 x10-7 A) 7. Two 20 turns coil 1 and coil 2 are tightly wrapped on the same 2.0 cm diameter cylinder
