A current-carrying straight wire is held in exactly vertical position. If the current passes through this wire in the vertically upward direction, what is the direction of magnetic field produced by it ? Name the rule used to find out the direction of magnetic field.

Give the arrangement of magnetic field lines around a straight wire and state the rule to find the direction of magnetic field.

If the current flows through a straight wire vertically upwards(out of page).How the direction field lines are?

In the straight wire A, current is flowing in the vertically downward direction whereas in wire B the current is flowing in the vertically upward direction. What is the direction of magnetic field : (a) in wire A ? (b) in wire B ? Name the rule which you have used to get the answer.

On what factor does the direction of the magnetic field produced by a current - carrying straight wire depend ?

How can we find the direction of magnetic field due to straight wire carrying current?

A wire carries current toward the north. In the region beneath this wire, What is the direction of the magnetic field due to the current ?

In the alongside figure a straight conductor B is carrying current in the vertical downward direction. What will be the direction of magnetic field lines around the conductor?

If the current in a wire is flowing in the vertically downward direction and a magnetic field is applied from west to east, what is the direction of force on the wire ?

Draw the magnetic field lines around a straight conductor carrying current. Name and state the rule to find the direction of magnetic field.

The magnetic field associated with a current-carrrying conductor is in anticlockwise direction. If the conductor was held along the east-west direction, what will be the direction of current through it ? Name and state the rule applied to determine the direction of current ?
