Induced electric field due to to changing magnetic flux are more readily observed than induced magnetic field due to changing electric field. Why? |
|
Answer» SOLUTION :The CHANGING electric FIELD PRODUCES displacement current, which is very small and hence the magnetic field set up by it is also small, the same cannot the be observed easily. In an a.c. circuit displacement current can be increased by increasing the ANGULAR frequency of current. This would increase the iduced electric field due to changing magnetic flux can be increased by taking more number of turns of the coil. The induced e.m.f. in different turns of the same coil are added up, resulting in induced electric field which is easily observed. |
