How could the direction of a magnetic field be determined by making only qualitative observations of the magnetic force on a straight wire carrying a current?

Short Answer

Expert verified

How could the direction of a magnetic field be determined by making only qualitative observations of the magnetic force on a straight wire carrying a current?

Step by step solution

01

About current and magnetic field.

If we put a wire carrying a current perpendicular to the magnetic field it will bend to one side. The direction of the current, the magnetic field and the direction of the bending of the wire make right trihedron and simply by analysing this we can determine the direction of the field which has to satisfy mentioned conditions.

02

Conclusion.

Hence, the direction of the current, the magnetic field and the direction of the bending of the wire make right trihedron and simply by analysing this we can determine the direction of the field.

A25.0-Ωbulb is connected across the terminals of a12.0-Vbattery having3.50Ωof internal resistance. What percentage of the power of the battery is dissipated across the internal resistance and hence is not available to the bulb?

A battery-powered global positioning system (GPS) receiver operating 9.0 V on draws a current of 0.13 A. How much electrical energy does it consume during 30 minutes?

In an L-R-C series circuit, what criteria could be used to decide whether the system is over damped or underdamped? For example, could we compare the maximum energy stored during one cycle to the energy dissipated during one cycle? Explain.

BIO The average bulk resistivity of the human body (apart from surface resistance of the skin) is about 5.0Ω·m. The conducting path between the hands can be represented approximately as a cylinder 1.6 m long and 0.10 m in diameter. The skin resistance can be made negligible bysoaking the hands in salt water. (a) What is the resistance between the hands if the skin resistance is negligible? (b) What potential difference between thehands is needed for a lethal shock current of 100 mA ? (Note that your result shows that small potential differences produce dangerous currents when the skin is damp.) (c) With the current in part (b),what power is dissipated in the body?

When switch Sin Fig. E25.29 is open, the voltmeter V reads 3.08 V. When the switch is closed, the voltmeter reading drops to 2.97 V, and the ammeter A reads 1.65 A. Find the emf, the internal resistance of the battery, and the circuit resistance R. Assume that the two meters are ideal, so they don’t affect the circuit.
