- A prototype of an MRI consists of a set of 600 coils each having a radius of 0.20 m. To test its efficiency a 1.8 T magnetic field oriented perpendicular to the plane of the coils is shut off over a 3.2 second time interval. What is the induced current in the coils? The resistance is 15ohmsA long fund rival solenoid with 100 turns per cm has a radius of 1.6 cm. Assume the magnetic field it produces is parallel to its axis and is uniform in its interior. A) what is its inductance per meter of length? B) if the current changes as shown on the graph, what potential difference is induced per meter?The current in a long solenoid of radius 6 cm and 22 turns/cm is varied with time at a rate of 3 A/s. A circular loop of wire of radius 8 cm and resistance 7 0 surrounds the solenoid. Find the electrical current induced in the loop (in HA). HA
- Question 1: When an external magnetic flux through a conducting loop decreases in magnitude, a current is induced in the loop that creates its own magnetic flux through the loop. How does that induced magnetic flux affect the total magnetic flux through the loop? O It does not affect the total magnetic flux. O It decreases and then increases the total magnetic flux. OIt increases the total magnetic flux. OIt increases and then decreases the total magnetic flux. O It decreases the total magnetic flux. Part (a) Some additional information, which is not included in the video, is that the SI unit of magnetic flux is the weber, denoted Wb. Using that information and the contents of the video, solve this numerical problem: A conducting loop, with a resistance of 2.0 Q2, encloses magnetic flux that is increasing at the rate of 2.0 Wb/s. The magnitude of the current induced in the loop is...
