A magnetic field is an invisible space around a magnetic object. A magnetic field is basically used to describe the distribution of magnetic force around a magnetic object.
Following are the methods of producing magnetic fields:
- By using a permanent magnet we can produce the magnetic field and it can be visualized by spreading iron fillings on a white paper and keeping a magnet beneath the paper.
- A current-carrying straight conductor produces the magnetic field.
- Different types of conductors such as solenoid and circular loop can be used to see the presence of a magnetic field.
