- A wire carrying 3.50 A of current passes through a 0.0425 T magnetic field at a 53.0 degree angle. If the magnetic force on the wire is 0.0345 N, what is the length of the wire in the field? (Unit = m)Two wires are separated by a distance of 5.0 cm and one carries a 11.0 A current up while the other carries a 9.5 A current down. If the wires are 1.2 m long then what is the force that each wire exerts on the other and is the force attractive or repulsive?A 0.829 m long wire carries a current of 8. If the wire experiences a force of 49.9 when it is at a 60-degree angle to an unknown magnetic field, what is the strength of the magnetic field?
- 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.A wire carrying a 30-A current passes between the poles of a strong magnet that is perpendicular to its field and experiences a 2.16-N force on the 4 cm of wire in the field.
