Explain different ways to induce a current in a coil.
Answer
We can induce current by
-
Moving the Conducting Wire inside a Fixed Magnetic Field
Hence, if we keep a conducting wire near the magnetic field of magnet and move it vigorously, current will be induced in it.
-
Keeping Wire (Conductor) Fixed and Changing Magnetic Field
Hence, if keep a wire fixed and change poles of magnet vigorously,current will be induced in wire.
-
Changing current in a nearby coil
If current is changed in a current carrying coil is placed near the conductor, magnetic field around it would change. Hence, current will be induced
