Question

Magnetic field increases as we go away from a magnet. Is the given statement true or false? Justify.

Answer 1

When electric current flows through a conductor, an induced EMF is created which in turn creates a magnetic field around it. The magnetic field lines form concentric circles around the conductor. The concentric circles become larger as we move away from the conductor because as the distance increases from the current carrying conductor the strength of the magnetic field fades away. Thus, the strength of the magnetic field is inversely proportional to the distance from the current carrying conductor. That is, as the distance increases the magnetic field decreases. Hence, the statement is false.
