Several points (a, b, c, d, e) are marked within and around this circle, each 1 cm apart. The points are aligned horizontally within the circle. This information helps in understanding the motion dynamics of protons in electromagnetic fields, relevant to students studying physics and electromagnetism.

Q2.4 Three wires are laid parallel to each other. Two are fixed (1 and 3) and one is moveable (2). They are all on a frictionless horizontal surface. Determine what will happen to wire 2 when the currents are all turned on simultaneously. Length of Wire fixed wire 20 cm Ij = 2A 12 = 4 A 2 moveable wire l3 = 1A 10 cm fixed wire 100 cm

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.
