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 of the wire is

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 ?

Explain the horizontal and vertical components of earth's magnetic field.

What is the magnetic induction at a distance of 5 cm from a straight wire carrying a current of 5 mA ?

A long vertical wire carriers a current of 10 amperes flowing upwards through it at place where the horizontal component of the earth's magnetic induction is 0.3 gauss. Then the total magnetic induction at a point 5 cm from the wire due magnetic north of the wire is

Earth's magnetic field always has a horizontal component expert at or Horizontal component of earth's magnetic field remains zero at

Magnetic field at a distance 'a' from long current carrying wire is proportional to -

A current of 5 flowing is passed throgh a straight wire of length 6 cm , then the magnetic induction at a point 5 cm from the either end of the wire is :
