A vertical wire in which current is flowing produces a neutral point with the earth's horizontal field at a distance of 5 cm from the wire in air . What is current , if `B_(H) = 0.18 xx 10^(-4) T`?

A long vertical wire in which a current is flowing produces a neutral point with the earth's magnetic field at a distance of 5 cm from the wire. If the horizontal component of the earth's magnetic induction is 0.18 gauss, then the current in the wire is

5 A current is flowing through a long straight conducting wire. What is the magnitude of magnetic field at a distance 10 cm from the wire ?

Current I is flowing through a vertical long wire in the upward direction. The magnetic field at a point on the east of the wire is

A vertical wire carries a current of 17 A. If the neutral point is observed at a distance of 10 cm from the wire, calculate the horizontal compoinent of earth's magnetic field .

A 10 cm length of wire with a mass of 20g is attached frictionlessly to the vetical segments of a wire in which a current I flows. The surrounding has horizontal field B=10^4G and the vertical direction is shown in fig. What must be the current I (in A) to maintain the 10cm wire in an equilibrium position?
