Solution
The correct option is
A
magnetic
Oersted's law states that a steady electric current
creates a magnetic field around
it. For a current carrying wire
The magnetic field lines encircle the current-carrying wire
The magnetic field lines lie in a plane perpendicular to the wire
If the direction of the current is reversed, the direction of the magnetic force reverses.
The strength of the field is directly proportional to the magnitude of the current.
The strength of the field at any point is inversely proportional to the distance of the point from the wire.
