Electric And Magnetic Fields

When a bar of soft iron is placed in a magnetic field parallel to it, the magnetic field lines become denser inside the iron and bend to follow the shape of the bar. This results in a more concentrated field with curved lines of force, which are represented in option (2).

A stationary charge (zero speed) generates only an electric field, not a magnetic field. Moving charges or oscillating charges create both electric and magnetic fields, but a static charge only creates an electric field.
