Magnetic Field. I have no idea how to solve these questions, please help!!!! MAGNETIC FIELDS SUMMARY You will measure how the magnetic field, B, produced by a coil varies with the current, I, in the coil. From your measurements, you w calculate the permeability constant Ho. Lastly you w use a magnet to induce a voltage in the coil. THEORY The magnetic field Batthe center of a circular coil (solenoid) of radius R with N turns that carries a current...
V: olorado River Run h It (Generator In a generator, an outside source of mechanical motion supplies the energy to move a magnet in a magnetic field. A generator works just like the moving magnet in a magnetic field (as in Part II) .Click on Show Field and observe the moving magnetic field Changing Changing Summary Lenz's Law states that the induced EMF opposes the change in the magnetic field. Imagine you were actually turning the water wheel by hand...

A generator has 534 circular loops with a diameter of 0.234 meters. The magnetic field applied through the region where our loops will spin is 0.456 T. It outputs an average of 66 MW. Assume the generator circuit is the source as described above in an AC-RL circuit where R is the equivalent resistance Req and the inductor L is an ideal transformer. 8. If the wire loops spin at 9.33x104 rev/min, what is the Vmax produced by the generator?...
A coil of wire is connected to a power supply, and a current runs in the coil. A single loop of wire is located near the coil, with its axis on the same line as the axis of the coil, The radius of the loop is 4 cm. At time ti the magnetic field at the center of the loop, due to the coil, is 0.7 T, in the direction shown in the diagram; the current in the coil is...
