In situations where a small signal must travel over a distance,a shielded cable is used in which the signal wire is surrounded by an insulator and then enclosed by a cylindricalconductor (shield) carrying the return current. Why is a“shield” necessary?
Ho Idlxf 4π 72 dB This problem checks your understanding of the term in the equation for the magnetic field due to a small "piece" of current, Consider a small piece of current (perhaps there's a wire) at location $ whose coordinates are (6 m, 2 m, 10 m). We would like to find the magnetic field at location P whose coordinates are (2 m, 5 m, 2 m). The term " is the distance between point S and point P. What is its value, in meters?
A copper ring and a gold ring of the same dimensions are placed in magnetic fields so that there is the same change in magnetic flux through them. Compare the induced electric fields and currents in the rings.
A straight line conductor of length 0.4 m is moved with a speed of 7m/s perpendicular to a magnetic field of intensity 0.9 Wb/m?. The induced e.m.f. across the conductor will be
An MRI technician moves his hand from a region of very low magnetic field strength into an MRI scanner’s 2.00 T field with his fingers pointing in the direction of the field. Find the average emf induced in his wedding ring, given its diameter is 2.20 cm and assuming it takes 0.250 s to move it into the field. Discuss whether this current would significantly change the temperature ofthe ring. Integrated ConceptsReferring to the situation in the above problem: (a) What current is induced in the ring if its resistance is 0.0100 ? (b) What average power is dissipated? (c) What magnetic field is induced at the center of the ring? (d) What is the direction of the induced magnetic field relative to the MRI’s field?
How can the voltmeter can be used to show characteristics of the induced current in electromagnetic induction?
Under what conditions might wires in a circuit where the current flows in only one direction emit electromagnetic waves (select all that apply)? When the current as a function of time is described by the function I(t) = 6.0 A When the current is switching between two distinct positive values When the current has any nonzero constant value When the current passes through a resistor
C2 (ii). A sinusoidal waveform is displayed on a C.R.O. screen, the time/cm switch is on 20 us/cm and the volt/cm switch is on 50 V/cm. The width of one complete cycle is 3.4 cm and the peak to peak distance is 5.6 cm. Determine the following: The frequency is The magnitude of the sine voltage is The amplitude is
An important feature of induced electric fields is that they have a potential function associated with them that is time dependent are parallel to the changing magnetic field that induces them. are not conservative. act only on moving electric charges, not on static ones.
