A 5mm long thin gold wire weighing 1microgram is placed on the plane of the earth and perpendicular to its magnetic field (Bearth = 5.0 x 10-5 T). Determine:
- The magnitude of current that would lift the wire from the ground.
- With the help of a drawing, show the direction of the current.
Thanks :)

Two long, thin parallel wires are placed 12.0 cm apart, as shown below. Each wire carries a 28 A current, but the currents are flowing in opposite directions. Determine the magnetic field vector at the point P, which is 10.4 cm from one wire, and 6.0 cm from the other. Please help me find the magnitude and the direction (θ).

A horizontal current-carrying wire that is perpendicular to the plane of the paper is placed in a uniform magnetic field of magnitude 2.6 mT that is parallel to the plane of the paper and points down. At the distance 1.0 cm to the right of the wire, the total magnetic field is zero. What is the magnitude of the current in the wire if the zero field point is 0.4 cm to the left of the wire?

A long, straight wire carrying a current of I1 =5.0 A perpendicular to the xy plane (page on a table) intersects the x-axis at the origin and points +z direction (out of page). A second, long wire carrying I2 = 12 A intersects the x-axis at x= 6.0 cm and points -z direction (into the page). Find the direction and magnitude of the net magnetic field due to these two currents at (x=0, y= 8.0 cm). First draw a neat...

3) A square wire with current in it, wrapped once, is placed in the x-y plane. It's sides have a length of 1.8 m and the magnetic moment produced by it is 6 A m2 in the +z direction. The square wire is then reshaped, using all the wire from the square, into a circle with the same current as the square. The circle is then placed into the x-y plane (first quadrant) such that it's magnetic moment is also...
