You have learned that a charge moving in an magnetic field can experience a magnetic force. Remarkably, anytime that a charged particle moves that particle produces its own magnetic field! The image below of magnetic compasses forming a circle around a current-carrying wire demonstrates the shape of the magnetic field. The magnetic field lines forms concentric circles around that wire. The strength of the field decreases with increasing distance away from the wire. If the current in the wire is 2.87A, what is the magnitude of the magnitude of the magnetic field (in μT, or micro-Tesla) a distance of 0.43m away from the wire?

A positive charge traveling with a speed of 9,678 m/s enters the deflection chamber of a mass spectrometer. In the deflection, chamber exists a uniform magnetic field of 0.55 T. The charge undergoes a deflection with a radius of curvature that is 0.024 m. If the charge is 1.602 x 10-19 C, what is its mass in atomic mass units*?
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.
