The very long cylindrical solenoid of (Figure 1) has a radius of 0.50 m and 1000 windings per meter along its length. A circular conducting loop of radius 1.0 m encircles the solenoid, with the long central axis of the solenoid passing through the center of the loop, and with the area vector of the loop parallel to the solenoid axis. The solenoid initially carries a steady current I, but the current is then reduced to zero during a 0.100-s time interval.

Part A

If the average emf induced in the loop during that interval is 0.80 V , what was the initial current magnitude?

A cylindrical tube that is 2.20 m long and has a radius of 150 mm is filled with water. It is oriented with its long central axis vertical, and it is open to the air at the upper end. A hole 80.0 mm in radius is drilled in the bottom, and the water is allowed to drain out. When the water level is half the height of the tube, (a) what is the speed of the water exiting through the...

A very long coaxial cable consists of a solid cylindrical inner conductor of radius 3.8mm , surrounded by an outer cylindrical conductor with inner radius 7mm , and outer radius 9.3mm . The region between the two conductors is filled with a waxlike insulating material to keep the conductors from touching each other. The inner conductor carries a current 4.65A , into the page, while the outer conductor carries a current 4.6A , out of the page. Part A Use...

A very light string is wound around a cylindrical spool of inertia M and radius R. The cylinder rotates on a frictionless horizontal axis with a moment of inertia 1 2MR2 . Attached to the end of the string is a block of inertia m, which pulls on the string and unwinds it from the cylinder, as the block falls. (a)Draw an extended free-body diagram for the cylinder, and a regular free-body diagram for the block. (b)Let m = 5...

A long straight cylindrical shell has an inner radius Ri and an outer radius R0.

A long straight cylindrical shell has an inner radius Ri and an outer radius R0. It carries a current I, uniformly distributed over its cross section. A wire is parallel to the cylinder axis, in the hollow region (r < Ri). The magnetic field is zero everywhere outside the shell (r > R0).We conclude that the wire: A) is on the cylinder axis and carries current I in the same direction as the current in the shell B) may be anywhere in...

Magnetic Field inside a Very Long Solenoid

The solenoid has length L, diameter D, and n turns per unit length with each carrying current .It is usual to assume that thecomponent of the current along the z axisis negligible.(This may be assured by winding two layers of closely spaced wiresthat spiral in opposite directions.)From symmetry considerations it is possible to show that farfrom the ends of the solenoid, the magnetic field isaxial.Which figure shows the loop that the must beused as the Ampèrean loop for finding Bz(r) for...

A solenoid (coil) of radius R has 10 turns per centimeter. It is 10cm long, and the coiled wire carries a current I. In addition to the coil of wire, a second wire runs right down the central axis of the solenoid, carrying a current of 2I. (The solenoid wire doesn't intersect this second wire, because the former wraps around the latter, always a distance R away.) A) Find the magnitude of the total magnetic field at a distance R/2...
