A flexible loop as shown in the figure below has a radius of 14 cm and is located in a region where the magnetic field strength is 0.11 T... the loop is then grasped at points A and B and stretched out so that its area becomes zero... (a) Assuming it takes 0.16s to close the loop to an area of zero, calculate the magnitude of the average induced voltage. (b) Determine the direction of the induced current running through the loop while its area is being reduced to zero.

The horizontal loop in the figure is placed in an external magnetic field B pointing downwards. If the external field B is increasing with time, then what is the direction of the induced current in the loop as viewed from above? t B Choose your answer from: Clockwise / Counterclockwise / No induced current

A square, single-turn wire loop { = 1.00 cm on a side is placed inside a solenoid that has a circular cross section of radius r = 3.00 cm, as shown in the end view of the figure below. The solenoid is 17.0 cm long and wound with 118 turns of wire. %3D (a) If the current in the solenoid is 3.10 A, what is the magnetic flux through the square loop? T m2 (b) If the current in the solenoid is reduced to zero in 2.95 s, what is the magnitude of the average induced emf in the square loop? V

The distance between two telephone poles is 44.0 m. When a 1.00-kg bird lands on the telephone wire midway between the poles, the wire sags 0.180 m. Draw a free-body diagram of the bird. How much tension does the bird produce in the wire? Ignore the weight of the wire.

A circle wire loop with 10 turns of wire has an area of 0.5 m2. It is initially in a 0.3 T magnetic field. Then over 0.5 seconds it is moved to a location with no magnetic field.   What is the magnetic flux? (The unit of flux is Weber, W)  What is the induced emf (voltage)?
