a) The transformer shown in Figure B2.1 consists of an infinitely long wire along the z-axis carrying a current I-cos ot, which couples to an iron toroid centred on the origin (0, 0, 0) and lying in the x-y plane. The iron toroid has a 100 turns coil tightly wound around it which induces a voltage Vemf as shown in Figure B2.1 The permeability of the iron toroid is r, and it has an outer radius of b, inner radius...
consider the toroid in figure 3.55 that is tightly wrapped with N tums of conductive wire. For an Amperian path with radius less than a, no current is enclosed and therefore the field is zero. Likewise, for radius greater than c. the net current enclosed is zero and again the field is zero. Use Ampere's circuital law to find an expression for the magnetic field at radius &, the center of the toroid. Consider the toroid in Figure 3.55 that...
A solenoid is constructed from a 20 cm long iron pipe. A copper wire of thickness 0.6 mm is wrapped tightly around the tube (assume there is no gap between the different coils). A) What is the magnetic field inside the solenoid if the wires carry a current of 50 A? B) A circular 8-turn loop of radius 4 cm is placed into the solenoid. What current is needed so that the loop experiences a maximum torque of 0.5 N*m?...
A current-carrying wire moves toward a coil A long straight wire carrying current I is moving with speed v toward a small circular coil of radius r containing N turns, which is attached to a voltmeter as shown. The long wire is in the plane of the coil. (Only a small portion of the wire is shown in the diagram.) Voltmeter N turns radius r The radius of the coil is 0.02 m, and the coil has 11 turns. At...
The magnetic flux that passes through one turn of a 10-turn coil of wire changes to 3.0 Wb from 9.0 Wb in a time of 0.024 s. The average induced current in the coil is 100 A. What is the resistance of the wire?
A long straight wire carrying a current of 2.03 A moves with a constant speed v to the right. A 120 turn circular coil of diameter 1.50 cm, and resistance of 3.25 u 2, lies stationary in the same plane as the straight wire. At some initial time the wire is to the left of the coil at a distance d = 13.0 cm from its center. 5.00 s later, the wire has moved to the right of the coil...
A square, single-turn wire coil L = 1.52 cm on a side is placed inside a solenoid that has a circular cross-section of radius r = 2.79 cm, as shown in the figure below.The solenoid is 18.0 cm long and wound with 107 turns of wire. If the current in the solenoid is 3.38 A, find the flux through the coil.If the current in the solenoid is reduced to zero in 3.37 s, calculate the magnitude of the average induced...

I am very lost! 1. The Biot-Savart Law states that a current induces a magnetic field of intensity H dL Free space pa dH a. If the wire is long and is carrying 10 A of current, find the magnetic field intensity H(p). then plot the field intensity vs. p on a graph for 1 sps 5 cm.
