- A 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?1.) Should the speed at which a magnet is moved through a coil of wire affect the measured peak voltage across the coil? If so, how? 2)If a magnet is moved through a coil of wire South pole first instead of North pole first, how should the measured voltage response be affected? 3) Should the number of individual coils in the wire have an effect on the measured emf? If so, how? 4) Below draw a graph of the expected magnetic flux through a point in the coil as a function of time as the magnet passes through the coil.ΔΦ. Vndeed=-N At ДФ %3D induced What will increase the Voltage produced by a moving magnet? OIncreasing the area of the loop under a constant B field. Increasing the number of loops in the coil. O Moving the magnet more rapidly O All of the above
- Induced EMF Below is a closed conducting loop within a magnetic field (for direction see picture). The loop is a circle with a radius of r = 5.00 cm. The magnetic field is decreasing in the direction shown at a rate of dB/dt = 157.0 mT/s. The circle wire has 305.0 loops around it. The wire has a total resistance of R = 2.80 Ohms. Magnetic Field (into the page) 8) What is the induced current around the wire in this system? (use a negative value for a clockwise current) Make sure to give your answer in an appropriate number of significant figures as well as including units with your answer. Your Answer: Answer units PLEASE TAKE OUT TRASH AT EOS IG18. If you have circular wire with a current I, and you in- crease I via external means, is there an induced current in the loop separate from the externally applied increase in I? A. B. C. Yes No Maybe, there's not enough information to tell
