- What is the right-hand rule for magnetism mathematically? What does it tell you about the physics of a system? I'm aware of the right hand rule, but want to make sure I understand what is meant by "mathematical" and "what it says about the physics of a system." If this question also asking for the mathematical formula?Describe the conditions where there is uniform circular motion for a charge in a magnetic field.A circular loop of wire carries a steady current. Sketch the magnetic field lines in a plane perpendicular to the plane of the loop. Mark, which side of the loop is the north magnetic pole and which is the south magnetic pole.
- Determine the magnetic field at the surface of the wire. Determine the magnetic field inside the wire, 0.50 mmmm below the surface. Determine the magnetic field outside the wire 2.5 mmmm from the surface.Consider a long, horizontal Large Wire with current of 10 A running through it. We want to levitate a horizontal, thin, 0.50 m length of wire above it. If the thin wire has a mass of 10 grams, and a current of 300 mA, how far above the Large Wire will it hover (net force of zero) due to magnetic and gravitational forces? A. If the thin wire hovers above the Large Wire due to their magnetic fields, are their currents going the same direction, or opposite directions. Explain. B. Draw a diagram and label the directions of currents, and all other relevant quantities and vectors. C. Find the distance above the Large Wire the small thin wire will hover (net force of zero). D. Would your answers to parts A and C change if we wanted to find a distance below (rather than above) the Large Wire that the smaller thin wire could hover, due to their magnetic fields. Explain. Don't calculate any values but draw a new diagram and explain how this situation compares to the problem above.Is it always true that magnetic force and electric field are in the same direction? Also, why is -vB opposite to magnetic force?
