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? 1. 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. 2. Draw a diagram and label the directions of currents, and all other relevant quantities and vectors. 3. Find the distance above the Large Wire the small thin wire will hover (net force of zero). 4. 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.

The accompanying figure shows a long, straight wire carrying a current of 10 A. What is the magnetic force on an electron at the instant it Is 20 cm from tire wire, traveling parallel to the wire with a speed of 2.0105m/s ? Describe qualitatively the subsequent motion of the election, For this current, what is tire permeability of the iron? If the current is turned off and then restored to 10 A, will the magnetic field necessarily return to 2.0 T?
A metallic particle is subjected to the influence of a magnetic field as it travels downward through a fluid that extends from plate A to plate B, as shown in Fig. 3. If the particle is released from rest at the midpoint C, s=100mm, and the acceleration is ? = (4.5?)m/s2, where s is in meters, determine the velocity of the particle when it reaches plate B, s=200mm, and the time it takes to travel from C to B. Completely show the solution including the integration/differentiation process. Thank you
