Problem And Solution Induced Elektromagnet [ Edition I ]

1. A wire loop diameter 9, beginning first 2 cm perpendicular to the magnetic field 1.5 T. The loop is rotated so that its surface is parallel to the direction of the field in 20 seconds. What is the average GGL induction in the loop?

2. A circular loop of wire diameter is 16 cm in a magnetic field 1.1 T. If he is removed from the magnetic field within 0.15 seconds, what is the average induction GGL?

3. A rectangular loop shown in the figure, driven to the magnetic field that leads into. Where the direction of the induced current?

4. The magnetic north pole in an image is inserted into a coil. Where the direction of the induced current through the resistor R?

5. Magnetic flux, which passes through two coils of wire coil, changed from -30 to 38 Wb Wb in 0.42 seconds. What is the emf induced in the coil?

6. The surface of a 7.2 cm diameter wire coil is initially parallel to the magnetic field of 0.63 T pointing upwards. In the interval of 0.15 sec, the terrain changed to 0.25 T leads down. What is the average GGL induction in a coil?

7. (A) If the resistance resistor in the figure is raised slowly, where the direction of the induced current in the small loop inside the loop? (B) what if the small loop is placed on the left side out of the loop?

8. Where the direction of the induced current in the circular loop on each piece in the picture?

9. If the solenoid on the picture drawn of the loop as the picture, where the direction of the induced current in the loop?

10. The magnetic field, which is perpendicular to the loop of wire diameter 20 cm, changing from +0.52 to -0.45 T T in 180 milliseconds, where "+" means the direction of the field away from the observer and "-" means the direction of the field toward the observer. (A) Calculate the induced emf m, (b) Where the direction of the induced current?
