|
| 01. A loop of wire of area 1m2 is placed perpendicular to a uniform magnetic field of 1Wbm-2. If the field is uniformly increased to 2Wbm-2 in a time of 10 seconds, find the induced EMF. |
| |
| Suggested solution: |
| |
| A = 1m2, B1 = 1Wbm-2, B2 = 2 Wbm-2, t = 10s, E = ? |
| |
| Initial magnetic flux, f1 = B1A = 1Wbm-2 x 1m2 = 1Wb |
| |
| Final magnetic flux, f2 = B2A = 2Wbm-2 x 1m2 = 2Wb |
