Following are the methods of producing magnetic fields:
By using a permanent magnet, we can produce a 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 a magnetic field.
Different types of conductors such as solenoid and circular loop can be used to see the presence of magnetic field.Answered by Shivani Kumari | 1 year ago
State the rule to determine the direction of an
(i) magnetic field produced around a straight conductor carrying current,
(ii) force experienced by a current-carrying straight conductor placed in a magnetic field which is perpendicular to it, and
(iii) current induced in a coil due to its rotation in a magnetic field.
