A horizontal wire with a mass per unit length of 0.2 kg/m carries a current of 2 A in the +x-direction. If the wire is placed in a uniform magnetic flux density B, what should the direction and minimum magnitude of B be in order to magnetically lift the wire vertically upward? (Hint: The acceleration due to gravity is g= - z9.8 m/s2.)

A horizontal wire of length 1.0 m carries a current of 48 A to the right. A second wire with a length of 0.5 m and a mass of 0.50 kg is suspend 0.30 m above the first wire. In what direction(left or right) does the current in the upper wire have to flow in order to be suspended against the force of gravity? What is the magnitude of the magnetic field (in mu T) due to the bottom wire...
A physics instructor performs a demonstration where a current-carrying wire is made to levitate. The wire has a mass per unit length of 0.590 g/cm and carries a current of 2.06 A horizontally to the south. Find the magnitude and direction of the minimum magnetic field needed to lift this wire vertically upward. (Enter the magnitude in T.) Magnitude:? Direction:?
3. A straight wire of mass 200 g and length 1.5 m carries a current of 2 A. It is suspended in mid-air by a uniform horizontal magnetic field B. What is the magnitude of the magnetic field?
Consider the system pictured in the figure below. A 14.4-cm horizontal wire of mass 15.2 g is placed between two thin, vertical conductors, and a uniform magnetic field acts perpendicular to the page. The wire is free to move vertically without friction on the two vertical conductors. When a 4.55-A current is directed as shown in the figure, the horizontal wire moves upward at constant velocity in the presence of gravity (a) What forces act on the horizontal wire? (Select...
4. A horizontal wire of length 3.0 m carries a current of 6.0 A and is oriented so that the current direction is 50 degrees below the negative x-axis.
