What will be the value of vertical component and total intensity of earth field at place where dip is `60^@`. Horizontal component is 0.3G.

Find the value of the vertical component and resultant intensity of the earth's magnetic field at a place where H is 0.2 G and angle of dip is 60°.

Where is the vertical component of earth's magnetic field zero?

Calculate angle of dip at a place, where horizontal and vertical component of earth's field are equal.

In the magnetic meridian of a certain place, the horizontal component of the eath's magnetic field is 0.26G and the dip angle is 60^@ . What is the magnetic field of the earth at this location?

Two rails of a railway track insulated from each other and the ground are connected to a milli voltmeter. What is the reading of millivoltmeter when the train travels at speed of 180 km/h along the track, given that the horizontal component of earth's magnetic field is 0.2*10^(-4) wb/m and the rails are separated by 1 meter.
