S.I. unit of Magnetic flux is – |
| A. | weber |
| B. | weber/m |
| C. | weber/m⁴ |
| D. | weber-m² |
| Answer» A. weber | |
|
Explanation: The SI unit of magnetic flux is the Weber (Wb) (in derived units: volt-seconds). It is the magnetic flux that, linking a circuit of one turn, would produce in it an electromotive force of 1 volt if it were reduced to zero at a uniform rate in 1 second. It is named after the German physicist Wilhelm Eduard Weber. The CGS unit of magnetic flux is Maxwell. |
