A current-carrying straight conductor is placed in the east-west direction. What will be the direction of the force experienced by this conductor due to the Earth's magnetic field? How will this force get affected on: (a) reversing the direction of flow of current, (b) doubling the magnitude of current?

A wire placed along east, west direction carries a current of 5A from west to east direction. Determine the magnetic field due to a 1.8 cm piece of wire at a point 150 cm north, east from the piece?

A wire placed along north-south direction carries a current of 10 A from south to north. Find the magnetic field due to a 1 cm piece of wire at a point 200cm north-east from the piece.
