Basic Electrical Mcqs

Q.  Magnetic flux has the unit of

a. Newton
b. Ampere-turn
c. Weber
d. Tesla


ANSWER: See Answer
 
The unit of magnetic flux is called Weber in honor of famous scientist Wilhelm Eduard Weber (1804 – 1891). Magnetic flux has also another unit named Maxwell. 1 Maxwell = 10-8 Weber.
