Question

Magnetie field of a eurrent carrying loop (5 points) A current carrying loop of wire lies flat on a table top. When viewed from above, the current moves around the loop in a counterclockwise sense. What is the direction of the magnetic field caused by this current, outside the loop? The magnetic field a. Circles the loop in a clockwise direction. b. Circles the loop in a counterclockwise direction. c. Points straight up. d. Points straight down Magnetic field of a solenoid (15 Points) 2. A solenoid used in plasma physics experiment is 10 cm diameter, 10 m long and carriesa 35 A current to produce a 100 mT magnetic field. How many turns are there in the solenoid ? 3. A solenoid is wound with 700 turns on a form 4 cm in diameter and 50 cm long. The windings carry a current in the sense that is shown. The current produces a magnetic field, of magnitude 4.1 mT, at the center of the solenoid. In the figure, the current in the solenoid windings is closest to: 4 cm A)3.5A B)4.33A C)2.6A D) 2.33 A

Explanation / Answer

1-

By use of right hand rule, turn all fingers in the direction of current then thumb shows the direction of magnetic field .

Hence, here option (C) is correct.point straight up.
