Explain with the help of a labelled diagram the distribution of magnetic field due to a current through a circular loop. Why is it that if a current carrying coil has ‘n’ turn, the field produced at any point is a times as large as that produced by a single turn? (b)How does an electromagnet differ from a bar magnet or permanent magnet? |
