Answer 2

Answer:

It's True

Explanation:

It is difficult to manually load and transport heavy scrap iron. Therefore, a permanent magnet of a very big size is necessary and this cannot be easily created. Hence, we create a powerful electromagnet by passing a current through a big iron disc. Thus, the big disc becomes powerful magnet and the scrap iron gets attracted to it, which can be easily loaded and transported.
