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.

Two metal spheres are hanging from nylon threads. When you bring the spheres close to each other, they tend to attract. Based on this information alone, discuss all the possible ways that the spheres could be charged. Is it possible that after the spheres touch, they will cling together? Explain.

Two parallel-plate capacitors, identical except that one has twice the plate separation of the other, are charged by the Same voltage source. Which capacitor has a stronger electric field Between the plates? Which capacitor has a greater charge? Which has greater energy density? Explain your reasoning.

The power rating of a light bulb (such as a 100-W bulb) is the power it dissipates when connected across a 120-V potential difference. What is the resistance of (a) a 100-W bulb and (b) a 60-W bulb? (c) How much current does each bulb draw in normal use?

A 1500-W electric heater is plugged into the outlet of a 120-V circuit that has a 20-A circuit breaker. You plug an electric hair dryer into the same outlet. The hair dryer has power settings of 600 W, 900 W, 1200 W, and 1500 W. You start with the hair dryer on the 600-W setting and increase the power setting until the circuit breaker trips. What power setting caused the breaker to trip?

When two point charges of equal mass and charge arereleased on a frictionless table, each has an initial acceleration(magnitude) a0. If instead you keep one fixed and release the otherone, what will be its initial acceleration: a0,2a0,or a0/2? Explain.
