FIGURE EX30.8 shows a diameter solenoid passing through the center of a diameter loop. The magnetic field inside the solenoid is . What is the magnetic flux through the loop when it is perpendicular to the solenoid and when it is tilted at a angle?
The magnetic flux through the loop when it is perpendicular to the solenoid,
and when it is tilted at angle,
A magnetic flux seems to be the magnitude of magnetic field which passes through some kind of ring of area . If the magnetic field lies straight towards the plane's normal, This magnetic flux was provided by
The magnetic flux, however, would be supplied by if the magnetic field forms an angular position only with planes.
The inclination of the parallel solenoid is perpendicular to the area's normal, hence the inclination is zero . The flux does have a region equivalent to the solenoid's sector, as well as any magnetic field beyond this zone had zero flux. The solenoid has a diameter of . As a result, the area is
Then, you put the data for , and to the equation (2) to obtain
The area would be tilted by the angle of , and thus surface area in the another instance would be
Then, you put the data for , and in the equation (2) to obtain
The square loop shown in moves into a magnetic field at a constant speed of.The loop has a resistance of , and it enters the field at
a. Find the induced current in the loop as a function of time. Give your answer as a graph of ii versus from to
b. What is the maximum current? What is the position of the loop when the current is maximum?
81. III In recent years it has been possible to buy a capacitor. This is an enormously large amount of capacitance. Suppose you want to build a oscillator with a capacitor. You have a spool of 0.25-mm-diameter wire and a -diameter plastic cylinder. How long must your inductor be if you wrap it with 2 layers of closely spaced turns?
